What is the a242 type 1 steel channel continuous casting

The a242 type 1 steel channel plate products have passed the EU CE certification, and have been recognized by China, France, the United States, the United Kingdom, Germany, Italy, Japan, South Korea and other eight classification societies for high-strength ship plates. The steel strand products have passed the United States (PTI) certification. The a242 type 1 steel channel products enjoy a high reputation in the domestic and foreign markets. The products are applied to national key projects and sold to 37 countries and regions such as EU, Middle East, Southeast Asia and America.

Hot rolled steel for cold forming can be divided into general purpose, stamping, deep drawing and ultra deep drawing according to its use. Common grades include a242 type 1 steel channel, DD11, DD12, SPHC, SPHD, SPHE steel. Hot-rolled steel for cold forming produced by our company uses low-carbon component, and has good stamping performance, welding performance and high dimensional accuracy. This material is widely used in various cold forming industries.

The steel plate and strip after hot rolling treatment are generally called hot rolled plate. Compared with other steel plate processing industries, a242 type 1 steel channel, hot rolled plate has these characteristics. First, low hardness, easy processing. Compared with other steel needs special mechanical equipment, hot rolled plate is a very convenient for processing. Second, good ductility, not easy to break, good compression capacity, long service life. Third, the manufacturing process is simple, and the price and cost are relatively cheap compared with other steels.

The common delivery status of a242 type 1 steel channel, SA516 Gr 70 plate is as follows:
1) SA516 Gr 70 plate quenching: the process of rapid cooling after heating to the temperature above the phase transformation point.
2) SA516 Gr 70 plate normalizing: after heating above the phase transition temperature, it is cooled normally (in air).
3) SA516 Gr 70 plate annealing: heating to above the phase transition temperature, cooling slowly.
4) SA516 Gr 70 plate tempering: after quenching, it is heated to a certain temperature (lower than the quenching temperature), kept warm, and then cooled.

20# seamless steel pipe chemical composition: C: 0.07-0.23, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.25, Ni: 0.30, Cu: 0.25. 20# seamless steel pipe mechanical properties: recommended heat treatment temperature: 910℃, tensile strength: 410 MPa, yield strength: 245 MPa, elongation: 25%, impact energy is not required. 20# seamless steel pipe hardness is higher than 10# seamless steel pipe. a242 type 1 steel channel, 20# seamless steel pipe has good weldability, no temper brittleness, and its machinability can be improved by water quenching. 20# seamless steel pipe can be used to make welded components, as well as parts with small load after forging, hot stamping and cutting.
