What is the hot sale carbon steel sa573 Grade 70 density

Focusing on the energy conservation and emission reduction objectives proposed by the municipal government, the company gives full play to the advantages of hot sale carbon steel sa573 Grade 70 circular economy formed after the comprehensive completion and operation, and vigorously promotes the implementation of energy conservation objectives. Through measures such as energy saving, technological innovation and hot sale carbon steel sa573 Grade 70 management strengthening, the energy saving target of annual reduction of added value energy consumption by 7%. It has made great contribution to energy saving of over completion.

BBN can provide hot-rolled and cold-rolled ASTM A285 steel plates, as well as special processing and cutting (any size and shape) drilling, welding, milling, hot sale carbon steel sa573 Grade 70 processing and steel structures according to drawings. Welcome new and old customers to purchase ASTM A285 steel plate from BBN.

After quenching and tempering, 40Cr alloy steel plate and hot sale carbon steel sa573 Grade 70 sheet have good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel hot sale carbon steel sa573 Grade 70 is good. It can be hardened to Ф28 ～ 60mm during water quenching and Ф15 ～ 40mm during oil quenching. In addition to quenching and tempering, this steel is also suitable for cyanidation and induction hardening. The cutting performance is better. When the hardness is HB174 ～ 229, the relative cutting workability is 60%. 40Cr alloy steel is suitable for making medium-sized plastic molds.

The wear-resistant composite plate, hot sale carbon steel sa573 Grade 70 should be pre heat treated to eliminate the residual stress produced in the machining process. If conditions permit, vacuum heating quenching and cryogenic treatment after quenching should be selected as far as possible. On the premise of ensuring the hardness of steel plate, pre cooling, step cooling and quenching or high temperature quenching should be selected as far as possible. For some wear-resistant composite plates, pre heat treatment, aging heat treatment and quenching, tempering and nitriding heat treatment can be used to control the accuracy of the wear-resistant composite plate.
