cold rolled oriented silicon steel strip (sheet) represents: times of DQ + iron loss value (at the frequency of Hz， the magnetic induction peak with sinusoidal waveform is the unit weight iron loss value of T) + times of thickness value. Sometimes G is added after the iron loss value to indicate high magnetic induction. For example， dq represents cold-rolled oriented silicon steel strip (sheet) with iron loss value of and thickness of .mm. Now the new model is q.
6It is generally suitable for the welding of thin plates below mm， with the characteristics of beautiful weld formation and small welding deformation.

Stainless steel is mainly used in the automobile industry，316L stainless steel pipe accounting for more than % of the total consumption of automobile stainless steel，430F stainless steel plateInspection work to be done before operation and % of it is ferritic stainless steel. The exhaust gas generated by the automobile engine passes through the exhaust gas inlet pipe， front pipe， hose， converter and central pipe. The commonly used steel grades of exhaust system are L l， etc. the automobile mainly makes Stainless steel welded pipe is used. It is estimated that the stainless steel pipe used in automobile accounts for about % of the consumption of stainless steel pipe in the whole downstream. L stainless steel pipe， s stainless steel pipe and L stainless steel pipe are provided for a long time， with complete products， excellent quality and favorable price. The proportion of stainless steel pipe and welded pipe is about :.
The shielding gas is argon with a purity of %. When the welding current is ~ a， the argon flow is ~ lmin，316L stainless steel pipe and when the current is ~ A， the argon flow is ~ lmin.

As long as it is a socket connected stainless steel wire， buttress must be set through calculation.
Stainless steel is a common steel in stainless steel， 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，316L stainless steel pipe stainless steel coil and other building materials. As a very important building material， stainless steel is widely used in industry，430F stainless steel plateInspection work to be done before operation construction industry， home decoration industry and food and medical industry. It is one of the indispensable materials in life! So what items are made of stainless steel in our life? Lets have a look!
hModel & mdash; Martensite (high strength chromium steel)， good wear resistance and poor corrosion resistance.
HThe inner and outer surfaces of steel pipes shall be free of cracks， folds， crazing， cracks， rolling folds， delaminations and scabs. These defects shall be completely removed (except for pipes for machining). After removal the wall thickness and outer diameter shall not exceed the negative deviation. Other minor surface defects that do not exceed the allowable negative deviation may not be removed.
NQuotation sheetRelevant information stainless steel export is an important part of Chinas export economy. It plays an important role in stimulating Chinas economic growth. However，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 from the current situation of Chinas stainless steel foreign trade， Chinas stainless steel export has encountered great resistance.
gCIt has excellent stress corrosion cracking resistance. Even duplex stainless steel with low alloy content has higher stress corrosion cracking resistance than austenitic stainless steel， especially in the environment containing chloride ions. Stress corrosion is a prominent problem that ordinary austenitic stainless steel is difficult to solve.
Extrusion method means that the heated tube blank is placed in a closed extrusion cylinder， and the perforated rod moves together with the extrusion rod to extrude the extrusion part from the smaller die hole. This method can produce steel pipes with smaller diameter.
systemkThe linear expansion coefficient of austenitic stainless steel is lower than that of austenitic stainless steel， suitable for connection with carbon steel， and has important engineering significance， such as the production of composite plate or lining.
FInspection: after crimping， check the crimping size with a special gauge.
At this time， we usually answer directly: no! What we produce is stainless steel decorative pipe， which belongs to stainless steel slotted pipe. It can not be used as stainless steel water pipe. If you want to choose stainless steel water pipe you must choose stainless steel pipe.
d series & mdash; Chromium nickel austenitic stainless steel.
dCCorrosion test: the industrial corrosion-resistant steel pipes provided shall be tested for corrosion resistance according to the standard provisions or the corrosion agreed by both parties， and there shall be no tendency of intergranular corrosion.
For example， the raw material difference of the three materials， such as and
