Recommended: Grade Q235A alloy steel pipe and Q235B alloy steel pipe have difference (1) stainless steel polishing machine output good beam quality, including mode and mold stability; (2) stainless steel polishing machine output power is large enough (this is the key to speed and effectiveness), whether the energy is stable (usually requires stability of 2%, in some occasions is required 1%, so as to process the ideal effect); (3) stainless steel polishing machine should have high reliability, should be able to work continuously in harsh industrial processing environment; (4) stainless steel polishing machine itself should have good maintenance, fault diagnosis and chain function, downtime should be short; (5) the operation is simple and convenient, the control key function is clear, can refuse illegal operation, protect the stainless steel polishing machine from damage. Stainless steel polishing machine should follow the principle of purchase: stainless steel polishing machine technology has many valuable characteristics. However, specific to a product is suitable for the use of this technology, should follow the following principles :(1) with other existing methods can not be solved, only with polishing processing method to solve; (2) the existing other processing methods can be solved, but if the polishing processing method can greatly improve product quality, improve production efficiency and significantly increase economic and social benefits; (3) to fully consider the processing process with polishing processing related to those matching links; (4) to pay attention to the application of polishing processing and conventional processing composite processing technology, in order to make full use of their strengths Metallographic Polish ,Struers Polishing Cloth Polishing,Struers Polishing Disc,Trojan Polishing Consumables TROJAN (Suzhou) Technology Co., Ltd. , https://www.trojanmaterials.com
The steel of Q235A alloy steel pipe and Q235B alloy steel pipe belongs to carbon steel. In the national standard GB700-88, the material quality of the Q235A and Q235B alloy steel pipes is mainly in the carbon content of the steel. The material quality of the Q235A alloy steel pipe is between 0.14 and 0.22? The material of the Q235B alloy steel pipe is not Do impact test, but often do temperature shock test, V-notch. Relatively speaking, the mechanical properties of steel made of Q235B alloy steel pipe are much better than steel made of Q235A alloy steel pipe. Under normal circumstances, steel makers have identified the signage on the finished product before it leaves the factory. The user can determine whether the material is Q235A alloy steel pipe, Q235B alloy steel pipe, or other materials on the identification plate.
