During butt backing， in order to prevent the back of the underlying weld bead from being oxidized the back also needs to be protected by gas.
1The dual phase microstructure of stress corrosion resistant stainless steel is helpful to improve the stress corrosion cracking resistance of stainless steel. In the presence of certain temperature， stress， oxygen and chloride， chloride stress corrosion will occur in austenitic stainless steel. Since these conditions are not easy the use of L and L is limited in this regard.
cModel & mdash& ldquo; Cutting tool level & rdquo; Martensitic steel， an early stainless steel similar to Brinell high chromium steel. It is also used for surgical tools，Stainless steel checkered plate such as automotive accessories. Good formability，316 stainless steel decorative pipeKey factors of market competition but poor temperature resistance and corrosion resistance.
Prepare materials and tools， prepare corresponding materials and tools， and check whether they match and apply.
FUjidaLow temperature processing --- martensitic stainless steel is quenched from austenitizing temperature and then cooled to very low temperature to promote the quenching of martensite. It is suitable for stainless steel which is easy to produce retained austenite.
AjRelevant 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.

Stainless steel is a common steel in stainless steel，Stainless steel checkered plate also known as stainless steel. It is characterized by high temperature resistance， excellent processing performance and good toughness， so it is made into a frequently used steel. Common in life are stainless steel pipe， stainless steel plate， stainless steel coil and other building materials. As a very important building material， stainless steel is widely used in industry， construction industry， with slightly higher carbon content， can obtain higher yield strength after appropriate heat treatment， and the hardness can reach hrc. It belongs to hard stainless steel. A common application example is & ldquo; Shaving blade & rdquo;. There are three common models: C and f (easy to process).
YThe cold working process performance and cold forming performance are much better than that of ferritic stainless steel.
VproductionThe welding performance is also much better than that of ferritic stainless steel. Generally，Stainless steel checkered plate preheating is not required before welding and heat treatment is not required after welding.
aPHot dip galvanized sheet hot dip galvanized sheet， which immerses the sheet into the molten zinc bath to make its surface adhere to a layer of zinc. It is mainly produced by continuous galvanizing process，316 stainless steel decorative pipeKey factors of market competition that is， the rolled steel plate is continuously immersed in the zinc melting bath to make galvanized steel plate. Liaocheng Suntory stainless steel plate weighing method: stainless steel plate: thickness (mm) x width (m) x Length (m) x density stainless steel plate: thickness (mm) x width (m) x Length (m) x density stainless steel plate: thickness (mm) x width (m) x Length (m) x density stainless steel basic weight (density)
cm thick stainless steel plate shall be processed with special cutting tools， such as laser cutting machine with large wattage
Windproof and ventilation. Where there is wind， please take measures to block the net， and take appropriate ventilation measures indoors.
Word of mouth recommendationdIn the grades of Japanese steel (JIS Series)， ordinary structural steel is mainly composed of three parts， which represent the material， such as s (steel) represents steel and f (ferrum) represents iron; The second part represents different shapes，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 types and uses， such as P (plate) represents plate， t (tube) represents tube， and K (kogu) represents tool; The third part represents the characteristic number， and the second s represents & ldquo; Structure & rdquo; (structure)， is the lower limit tensile strength of MPa， and the whole represents ordinary structural steel with tensile strength of MPa.
PStainless steel pipe can be divided into equal section pipe and variable section pipe according to the profile shape. Variable section pipes include conical pipes， stepped pipes and periodic section pipes.
Hydraulic saw grinding disc (manual saw wire cutting machine).
t — Ferritic stainless steel for decoration， such as automotive accessories. Good formability， but poor temperature resistance and corrosion resistance.
nEThe application of stainless steel pipe in the automobile industry is developing rapidly. In recent ten years stainless steel pipe materials have been widely used in public transportation tools such as buses， high-speed railway vehicles， household cars and so on!
L stainless steel pipe is a kind of hollow long round steel， which is mainly used for industrial transmission pipelines and mechanical structural components such as petroleum， chemical industry， medical treatment， food， light industry， machinery and instruments， etc. In addition， when the bending and torsional strength are the same， the weight is light， so it is also widely used in all kinds of manufacturing mechanical parts and engineering structures.
