a242 type 1 steel angle for general intermediate strength applications

Our company's a242 type 1 steel angle power boilers, heating furnaces of double bars, double high lines and medium and thick plates all adopt heat storage technology, which can fully use blast furnace gas; the ladle baking, Maerz active lime kiln and medium and thick plate heat treatment furnace all burn converter gas, which can improve the a242 type 1 steel angle utilization rate of secondary energy and realize negative energy steelmaking in steelmaking process.

a242 type 1 steel angle, Boiler steel plate is a kind of medium and heavy steel plate used to make important parts of boilers. From the material point of view, boiler steel plate can be divided into special carbon steel plate and low alloy heat resistant steel plate. According to the different working conditions, the boiler steel plate can be divided into two categories: manufacturing room temperature and medium temperature pressure bearing parts steel plate and manufacturing high temperature pressure bearing part steel plate. Boiler steel plate is widely used in petroleum, chemical industry, power station, boiler and other industries.

Our company provides a242 type 1 steel angle, A302 gr. B boiler plate for customers all over the world, which is used for pressure vessels, boilers, tanks and heat exchangers in oil and gas projects. The boiler steel plate of ASTM A302 grade B /A302 gr. B can be rolled with a maximum thickness of 300 mm, and the steel performance, including mechanical properties and chemical composition, can be guaranteed to fully comply with ASTM A302 / A302M standard.

The performance of heat treatment process reflects the difficulty of heat treatment and the tendency of defects of the steel. It mainly includes hardenability, superheat sensitivity, temper embrittlement tendency and oxidation decarburization tendency. The hardenability of a242 type 1 steel angle, alloy steel is high. The cooling method can be used slowly during quenching, which can reduce the deformation and cracking tendency of the workpiece. The addition of Mn and Si will increase the superheat sensitivity of steel. The strengthening effect of alloy elements on steel in quenching and tempering state is the most significant.

40Cr grade under GB/T 3077-2015 standard is a alloy steel bar material. a242 type 1 steel angle, 40Cr alloy chemical composition (C: 0.37 ~ 0.44, Si: 0.17 ~ 0.37, Mn: 0.50 ~ 0.80, Cr: 0.80 ~ 1.10, Ni: ≤0.30, P: ≤0.030, S: ≤0.030, Cu: ≤0.30, Mo: ≤0.10). Heat treatment: First quenching heating temperature (℃): 850; coolant: oil; Temperature heating temperature (℃): 520. 40Cr steel tensile strength (σb / MPa): ≥980. Yield point (σs / MPa): ≥785

BBN company is an industry leading steel service center that supplies a full line of hot rolled steel plate in a variety of sizes, grades and finishes. Hot rolled steel is an economical option that offers reliable performance and versatility. In the a242 type 1 steel angle hot rolled process, high temperature is used to heat the steel above its recrystallization point. In this state it becomes more malleable, allowing it to be easily formed into a variety of shapes. If you are interested in A36 hot rolled plates price, welcome to come and visit us.

The company formulates clear service process and service standard. To do a good job in after-sales service, first of all, clear service process and service standards should be formulated to let employees know which procedures to perform and which service standards to abide by.
