1600mm thickness astm a516 grade 70 hic for sale

Application of 30CrMnSiA steel, astm a516 grade 70 hic:30CrMnSiA steel is generally used after quenching and tempering. 30CrMnSiA steel is mainly used to manufacture various important parts with high load and high speed, such as gears, shafts, clutch friction plates, sprocket wheels, grinding wheel shafts, shaft sleeves, bolts, nuts, etc. 30CrMnSiA steel is also used for manufacturing wear-resistant parts with low working temperature and variable load welding components, such as blades, valve plates and non corrosive pipes and pipes of high-pressure blowers.

Compared with astm a516 grade 70 hic, boiler steel plates should have the following properties: (1) High medium temperature strength: low and medium pressure boiler drums use steel with a lower yield point, high pressure boilers use steel with a high yield point. (2) Good plasticity, impact toughness, cold bending and welding performance. (3) The notch sensitivity is small, that is, the sensitivity to the stress concentration caused by the opening of the steel plate surface and the welding of the pipe head is small.

Quenching is a heat treatment process in which steel parts are heated to above the critical temperature, and after proper heat preservation, the parts are quickly cooled to room temperature in water or oil, so that martensite transformation occurs. The hardness of the quenched astm a516 grade 70 hic increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of astm a516 grade 70 hic during tempering, while tempering determines the performance and life of the workpiece.

Over the years, the company has maintained long-term stable business relationships with major domestic steel mills and foreign steel companies.
