According to the steel structure, austenite ferrite ferrite martensite and precipitation hardening note: precipitation hardening (precipitation strengthening): refers to a heat treatment process in which the metal is hardened by the segregation zone of solute atoms in supersaturated solid solution and / or the desolved particles are dispersed in the matrix. For example, austenitic precipitated stainless steel can obtain high strength by precipitation hardening at ~ ℃ or ~ ℃ after solution treatment or cold working. That is, the supersaturated solid solution of some alloys is placed at room temperature or heated to more & amp; gt;& amp; gt;

1After hot rolling, it is subject to heat treatment and pickling treatment.

iMeasures to improve the welding quality of stainless steel pipe in order to ensure that the outer surface of stainless steel pipe is not damaged and purified, the maintenance of stainless steel pipe should be strengthened in each process of consumption,Stainless steel checkered plate avoid indirect contact between austenitic stainless steel and carbon steel processing platform or solid air.

Water quality requirements. Therefore relevant experts: building water supply pipes will eventually return to the era of metal pipes. According to foreign application experience,316L thick wall stainless steel pipePerformance and Application stainless steel pipe is recognized as one of the pipes with good comprehensive performance in metal pipe. Chemical analysis: carry out chemical analysis on the chemical composition of the material, and the chemical composition meets the standard requirements.

NBytcaHan Jianbiao, an analyst at Zoomlion steel, Chinas steel pipe exports have been only or tons per month, of which seamless pipe exports are only about tons per month.

DpOrganic substances (such as melons and vegetables, noodle soup, phlegm, etc.) adhered to the surface of stainless steel constitute organic acids in the presence of water and oxygen. For a long time, the corrosion of organic acids on the metal surface.

Cold formed alloys can be cut and cold formed. However,Stainless steel checkered plate due to its high strength and hardness, the alloy needs cold forming more than austenitic steel. Because of its high strength, springback should be fully considered.


& Ge; about thickness: cold rolled B plate (. & mdash; mm); hot rolled industrial plate No. (-mm) medium plate, chemical plate and high temperature plate; width: mm --- mm steel strip; , , , and mm coil plate and flat plate surface: B smooth surface, No. industrial surface, BA (K) mirror, K mirror,Stainless steel checkered plate wire drawing surface and frosted surface.

wProduction process of stainless steel welded pipe: raw material - strip - welded pipe - end repair - polishing - Inspection (spray printing) - Packaging - shipment (warehousing) (decorative welded pipe).

CHydraulic test shall be conducted for the steel pipe bearing fluid pressure to test its pressure resistance and quality. It is qualified if there is no leakage or expansion under the specified pressure. Some steel pipes shall also be subject to crimping test, flaring test and flattening test according to the standard or the requirements of the demander.

GLets seeFolding editing the principle of this paragraph when the stress of steel or sample exceeds the limit,316L thick wall stainless steel pipePerformance and Application even if the stress no longer increases, the steel or sample continues to have obvious plastic deformation. This phenomenon is called yield. We specialize in selling stainless steel plate, stainless steel coil, stainless steel belt and stainless steel pipe to ensure quality, service and quality. Your satisfaction is our pursuit! Welcome to inquire If PS is the external force at the yield point s and fo is the cross-sectional area of the sample, then the yield point & sigma; s = PS / fo (MPA), MPa is called MPa, which is equal to n (Newton) / mm (MPA = pa,tisco stainless steel sheet,taigang stainless steel sheet,stainless steel sheet,stainless steel coil,stainless steel strip,stainless steel tube-TISCO Stainless Steel Co.,Ltd PA: Pascal = n / m.

hLStainless steel capillary material: SUS / sus; Inner diameter mm-mm polished. Purpose of stainless steel capillary: automatic instrument signal tube, automatic instrument wire protection tube; Precision optical ruler circuit, industrial sensor, electronic equipment circuit protection tube; Safety protection of electrical circuit, capillary protection of thermal instrument and internal support of air core high-voltage optical cable. Stainless steel capillary characteristics: it has good flexibility, corrosion resistance, high temperature resistance, wear resistance, tensile resistance water resistance, and provides excellent electromagnetic shielding performance. Stainless steel hose can be bent into various angles and radius of curvature, and has the same flexibility and durability in all directions; The stainless steel hose has flexible pitch, good flexibility and no blocking and stiffness; The stainless steel threading hose has certain tensile resistance between the side buckles of each section to prevent the damage of the hose from exposing the lines laid inside the hose. It is a special product manufacturing enterprise integrating R & D, sales and service. It has long been specialized in selling stainless steel plate, Stainless steel pipe. The axial tension can withstand times of the nominal inner diameter. The yield strength of duplex stainless steel is more than twice that of ordinary austenitic stainless steel. This characteristic makes the designer reduce the weight when designing products, making this alloy more cost-effective than L. This alloy is especially suitable for - DEG; F/+° F temperature range. For applications beyond this temperature range, this alloy can also be considered, but there are some, especially for welded structures& middot; Pressure vessel, high pressure storage tank, high pressure pipeline, heat exchanger (chemical processing industry).

However, stainless steel is relative, and it is just ordinary stainless steel. Its better not to use it in a particularly polluted environment. You can rest assured to use stainless steel pipes in your daily life.


Since last year, foreign countries have frequently carried out & ldquo; Double inverse & rdquo; This has a great impact on Chinas stainless steel casting industry. Export is a large part of the development of Chinas stainless steel industry and occupies a huge market share in its industrial development. In the face of the current economic downturn and slow development speed, the development of Chinas stainless steel industry should continuously improve product quality, Better develop overseas trade and deal with trade protectionism, combine products with environmental protection, energy resources and cultural environment, tensile strength, elongation and hardness of various stainless steel coils meet the requirements, the stainless steel coils must undergo heat treatment such as annealing, solution treatment and aging treatment before delivery. The corrosion resistance of stainless steel coil mainly depends on

KWhen using this process, the following key points should be paid attention to: during the welding process, the correct included angle should be maintained between the welding handle, welding wire and weldment. The ideal caster angle of the welding handle nozzle is & deg; & mdash; & deg;, and the included angle between the welding wire and the weldment surface is & deg; & mdash; & deg;; the correct molten pool temperature should be changed by changing the included angle between the welding handle and weldment, changing the welding speed, etc Ensure beautiful weld formation (uniform width, no concave, over convex and other defects); during operation, the current shall be slightly larger than that when welding solid core welding wire, and the welding handle shall swing slightly to accelerate the separation of molten iron and molten coating, so as to facilitate the observation of molten pool

This kind of steel pipe can be divided into stainless steel seamless steel pipe and stainless steel welded steel pipe (slotted pipe). According to different manufacturing processes, it can be divided into several basic types: hot rolling extrusion, cold drawing and cold rolling. According to the section shape, it can be divided into circular pipe and special-shaped pipe. Circular steel pipe is widely used, but there are also some square rectangular, semi-circular, hexagonal Equilateral triangle, octagonal and other special-shaped stainless steel pipes.

bFor the length of welding arc, ~ mm is better for ordinary steel welding, and ~ mm is better for stainless steel welding. If it is too long, the protection effect is not good.

tGAfter hot rolling, it is subject to heat treatment and pickling treatment.
