S420ML steel tubing carbon steel usages

S420ML steel tubing, Manganese steel plate is a low alloy high strength steel plate with good weldability. Manganese steel plate is the main material of general pressure vessel. Manganese steel plate is mainly used to make engineering structural parts, roof beam of workshop and tower crane tower body. Manganese steel plate has high rupture strength and creep strength at high temperature and good impact toughness at low temperature. High strength steel is a kind of wear-resistant steel for heavy industry. Its application fields include quarrying, mining, mining, coal industry, casting and steel industry, etc.

Over the years, the company has trained a number of professional sales talents, enriched the concept of various marketing and customer service, and strengthened the business strength of the company. Now the company's business S420ML steel tubing department, marketing department and information department constitute the market development network; the finance department, personnel department, logistics department, shipping department, document department and S420ML steel tubing after-sales service department constitute the service customer network.

TMCP process is an important means to improve the comprehensive properties of steel. It can be used to produce ship plate, vessel plate, boiler plate, bridge steel, etc. Compared with the normalized steel of the same strength grade, TMCP can reduce the alloy content of the S420ML steel tubing steel, reduce the carbon equivalent and improve the welding performance. TMCP is more and more widely used in various types of steel rolling industry.

For low alloy high strength steel, the addition of small amounts of V, Ti, Nb, AI and other grain refining elements not only further improves the strength, but also improves the toughness of the steel. In S420ML steel tubing, low alloy high strength steel, rare earth element Re is sometimes added to eliminate harmful impurities in the steel, improve the shape and distribution of inclusions, and weaken its cold brittleness. A small amount of alloying elements has a significant effect on improving the mechanical properties of steel. For example, adding only 1% Mn to Q235 becomes Q345 steel, but its strength increases by nearly 40% to 345 MPa.

Our company will accept the product quality objection registration record, pass it to the S420ML steel tubing production unit and relevant departments, and timely coordinate the supervision of product S420ML steel tubing quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
