Q355NHE grade is a weather-resistant structural steel used in construction, bridges, and railway vehicles. Q represents yield strength, NH represents weather resistance, and E represents quality grade (A, B, C, D, E) composition. Q355NHE is an atmospheric corrosion-resistant steel plate, also called weather-resistant steel plate. It has the properties of high-quality steel such as strength, ductility, forming, welding, abrasion, high temperature, and fatigue resistance.

After quenching and tempering, 40Cr alloy steel plate and a516 grade 70 steel for bridge construction sheet have good comprehensive mechanical properties, good low temperature impact toughness and low notch sensitivity. The hardenability of steel a516 grade 70 steel for bridge construction 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.

What is a516 grade 70 steel for bridge construction, boiler steel consumption rate? The cost of the boiler, to a large extent, depends on the steel consumption of the boiler. The so-called boiler steel consumption rate refers to the tons of boiler steel used per 1t / h evaporation capacity of the boiler, also known as the boiler steel consumption per unit evaporation. The boiler steel consumption rate of boilers with different parameters, capacities and structures is different.
