How to improve toughness of JIS SM520C plates

When cutting extra thick JIS SM520C plates steel plates, the cutting speed should not be too fast. Many processing and production industries will encounter such problems, that is, in order to speed up the cutting of extra thick steel plates, many details will be ignored in the process of these process operations, so it is easy to produce waste parts, and some plates JIS SM520C plates will crack. So when cutting extra thick steel plates, you must pay attention to the speed, which can not be too fast. Low-speed processing can effectively improve work efficiency.

SM490B is a structural steel produced according to Japanese standard JIS G3106, with a strength σb of 490MPa.This standard applies to bridges, ships, vehicles, petroleum storage tanks, manufacturing plants, general construction and various engineering machinery, such as drilling rigs, electric shovels, electric wheel dump trucks, mining vehicles, and excavators used in mines and various engineering constructions.

"Hard and solid, honest commitment, practical effect". To strive for a solid enterprise foundation with hard work style; to promise first-class enterprise service with honest faith; to create efficient enterprise performance with practical spirit.

The tensile strength of seamless steel pipe is more than 8-10 times of that of ordinary steel, and its elastic modulus is better than that of steel, with excellent creep resistance, corrosion resistance and seismic resistance; the mechanical performance of seamless steel pipe is excellent, easy to machine, etc.; the seamless steel pipe JIS SM520C plates is highly elastic, reused in mechanical equipment, memoryless, deformation free, and antistatic.
