— General model; stainless steel. The GB brand is CrNi.
3cm thick stainless steel plate shall be processed with special cutting tools， so its name is considered. Decorative stainless steel pipe is used for decorative purposes. The stainless steel pipe for general decorative purposes is relatively thin. Because it is different from the manufacturing process of stainless steel product pipe， the price also varies greatly. The general production process of decorative stainless steel pipe is ordinary welded stainless steel pipe. Guangdong stainless steel product pipe stainless steel product pipe: generally， the surface of stainless steel product pipe is also a bright surface， and a small number of pipes with acid pickling industrial surface. As mentioned above，316L stainless steel plate stainless steel product pipe belongs to the purpose of stainless steel products，316L stainless steel coilWhat is the effect of fan blades on performance because the outer diameter size， mechanical properties， acid， Therefore， stainless steel pipes are generally used as anti-corrosion materials or hardware products in large chemical production enterprises. The production process of stainless steel pipes is one-time forming， and nitrogen protection is also added during welding.
Relevant information stainless steel export is an important part of Chinas export economy. It plays an important role in stimulating Chinas economic growth. However， from the current situation of Chinas stainless steel foreign trade， Chinas stainless steel export has encountered great resistance.
SBelvilleNational standard thickness of stainless steel pipe. Stainless steel pipe is a brand of stainless steel produced according to American ASTM standards. Before the national standard thickness of stainless steel pipe， there are stainless steel pipe national standard thickness national standard wall thickness table product name specification material price (yuan ton) rise and fall welded pipe points mm (& phi; mm) + welded pipe inch mm (& phi; mm)
VlThere are ba face，316L stainless steel plate b face， (white skin)， D face， (frosted)， HL (wire drawing) K face and other surfaces with good quality and brightness.
The welding alloy has good weldability. Professional sales of stainless steel plate， stainless steel coil， stainless steel belt， stainless steel pipe， large quantity， high quality and low price. Fire resistance - Waterproof - high temperature resistance，316L stainless steel plate strong and durable， safe and reliable. The performance of the alloy is that the welding metal and heat deteriorated part still maintain the same corrosion resistance，316L stainless steel coilWhat is the effect of fan blades on performance strength and toughness as the base metal. It is not difficult to weld， but its welding procedure needs to be designed so that after welding， it can maintain a good phase balance and avoid the precipitation of harmful metal phase or non-metal phase. Welding can be carried out in the following equipment: GTAW (TIG); GMAW (MIG); SMAW (“stick” electrode); SAW; FCW; And paw stainless steel features: compared with L and L austenitic stainless steel， duplex stainless steel alloy has superior performance in spot corrosion and crack corrosion resistance. It has high corrosion resistance. Compared with austenite， it has lower coefficient of thermal expansion and higher thermal conductivity.
Process performance inspection: flattening test， tensile test， impact test， flaring test，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 hardness test， metallographic test， bending test and nondestructive testing (including eddy current testing， X-ray testing and ultrasonic testing).
yWhen hoisting stainless steel pipes， public slings， such as hoisting belt and public collet number， shall be used. It is strictly prohibited to use steel wire rope to avoid scratching the surface; and when hoisting and placing， it shall prevent scratching caused by impact and collision. If there are surface scratches， arc traces and surface purification in the process of transportation， storage and processing， it must be completely cleaned， polished with an angle grinder， and then used Polishing sheet or metallographic sandpaper.
GRemarks: to ensure the nickel content of stainless steel strip and the mechanical properties of stainless steel strip， material certificate (Baogang material)， Japan Nippon Steel Material Certificate (Nippon Steel material)， etc. can be provided.
HGood reputationThe existence of medium temperature brittle zone requires strict heat treatment and welding process system to avoid the appearance of harmful phase and damage the performance.
nXStainless hot plate (grade I) GB- stainless cold strip (grade I)
Before connecting the pipe fittings， mark the depth on the pipe first， so as to prevent it from being inserted in place and stuck.
The difference between duplex stainless steel plate and ferritic stainless steel plate: the comprehensive mechanical properties are better than ferritic stainless steel， especially the plastic toughness， which is not as sensitive to brittleness as ferritic stainless steel.
Quality managementsHydraulic 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， cold drawn pipe and extruded pipe. Cold drawing and cold rolling are the secondary processing of steel pipe; Welded pipe is divided into straight seam welded pipe and spiral welded pipe.
When brown rust spots appear on the surface of stainless steel pipes cold-rolled pipe， this is a one-sided wrong view because the understanding of stainless steel pipe is not comprehensive enough. You should know that stainless steel pipe will rust under certain conditions.
xCheck whether the sealing ring of pipe fittings is complete and clean and whether the placement position is correct. If there is dirt， it must be cleaned up. If the sealing ring is damaged， it must be replaced again.
sO(IV) high level operation of steel plant and social inventory. The contradiction between market supply and demand spread to the circulation field， and the domestic steel inventory continued the growth trend at the end of the previous year. On March ， it reached a historical high of . million tons， an increase of . million tons over the previous high， including . million tons of construction steel inventory， accounting for % of the total inventory. After that， with the increase of seasonal consumption， the inventory gradually fell back to . million tons on July . The oversupply in the market also pushed up the inventory of steel mills. In mid March the steel inventory of key enterprises reached a historical record， reaching . million tons， a year-on-year increase of %， and decreased to . million tons in late June， stainless steel coil， stainless steel belt， stainless steel pipe and other products with complete types selling well at home and abroad， and has a long service life! Products lead the industry in wire products. Welcome to inquire. An increase of % over the same period in .
— After that， the second widely used steel is mainly used in food industry and surgical equipment. Molybdenum is added to obtain a special corrosion-resistant structure. Because it has better chloride corrosion resistance than it， it is also made & ldquo; Marine Steel & rdquo; To use. SS is usually used in nuclear fuel recovery units. Grade stainless steel generally meets this application grade.  Model & mdash; Except that the risk of weld corrosion of the material is reduced due to the addition of titanium， other properties are similar.
