What is the a516 grade 70 hardness with hot rolled

In the development process of more than 20 years, the company keeps pace with the times, keeps innovating its ideas, constantly adjusting its steel product a516 grade 70 hardness structure, constantly strengthening its comprehensive competitiveness, constantly improving its management level, and more importantly, forming its corporate culture of elements and personality. The company always strives to build itself a comprehensive competitive steel a516 grade 70 hardness supplier in the world.

a516 grade 70 hardness, Q345 angle steel has two kinds: unequal angle steel (two sides are not the same size) and equal angle steel (two sides are the same size). a516 grade 70 hardness, Q345 angle steel is widely used for mechanical processing, building structure, steel structure, etc.. In addition, Q345 angle steel can withstand - 40℃ low temperature at least and can be used in cold areas. The weight calculation formula of Q345 angle steel: 0.00785 * (side width + side width - side thickness) * side thickness, the value obtained is the weight per meter, and then multiplied by the length to calculate the weight of a piece.

Compared with 15Cr steel, 20Cr alloy has higher strength and hardenability. The critical hardening diameter in oil is 4-22mm, and the critical hardening diameter in water is 11-40mm, but the toughness is poor. This a516 grade 70 hardness alloy steel a516 grade 70 hardness still has a tendency to grow grains during carburization, and direct quenching at lower temperature has a greater impact on impact toughness, so secondary quenching is required after carburization to improve the toughness of the core of the part, and there is no temper brittleness.

Weathering steel plates have an excellent corrosive resisting property like resistance to crevice and pitting corrosion, resistance to corrosion and oxidation. This plate also has resistance to chloride corrosion cracking and stress corrosion. These plate are not affected very easily by acids and environmental rust and works in the sulfide atmosphere. a516 grade 70 hardness, Weather resistant steel plates have excellent workability, formability, easy to install, easy to fabricated, machinability, durability, reliability.

A588 Grade A steel plate is for high strength low alloy structural steel with 345Mpa minimum yield point to 100mm thickness."When propertly exposed to the atmosphere, A588 Grade A is suitable for many applications in the bare condition. a516 grade 70 hardness, A588 Grade Acould be produced in 200mm in our company.

Our company has its own steel plate manufacturing plant, processing plant and steel pipe plant.
