What is the difference between Q235A steel and Q235B steel? First, The carbon content of Q235A steel is 0.22%, higher than that of Q235B steel, which is 0.20%. The sulfur content of Q235A steel is 0.050%, higher than that of Q235B steel, which is 0.045%. Second, P265GH equivalent, Q235 material belongs to carbon structural steel. The English letters A and B at the back have different meanings. They are impact temperature requirements. Q235A steel is not subject to impact, while Q235B steel is subject to 20 ℃ room temperature impact.

The company adheres to the business philosophy of "excellent quality and integrity", aims to create a first-class enterprise in the p265gh equivalent industry, takes circular economy and resource reuse as the main line, takes energy conservation, emission reduction and sustainable development as the purpose, relies on advanced equipment, perfect transportation infrastructure and good reputation, and strives to become a leading enterprise in the p265gh equivalent industry with scientific management, high quality, first-class service and harmonious development

Nickel element is mainly used to form and stabilize the austenite structure, so that the p265gh equivalent steel has good mechanical properties, corrosion resistance and process performance. Molybdenum can quickly passivate stainless acid-resistant steel, and improve the corrosion resistance to solutions containing chloride ions and other non-oxidizing media. Titanium and niobium are usually used to fix the carbon in alloy steel and make it generate stable carbides to reduce the harmful effect of carbon on the corrosion resistance of alloy steel.

The alloying principle of low alloy high strength steel plate mainly uses solid volume strengthening, fine grain strengthening and precipitation strengthening produced by alloy elements to improve the strength of low alloy high strength steel plate, p265gh equivalent. At the same time, the effect of fine grain strengthening on the reduction of ductile brittle transition temperature of low alloy high strength steel platel is used to offset the adverse effect of carbon nitride precipitation strengthening on the rise of ductile brittle transition temperature of steel, so that low alloy high strength steel plate can obtain high strength while maintaining good low temperature performance.

We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
