ASTM A709 carbon steel material I beams

We have very professional workshops for thin plates/ coils, ASTM A709 carbon steel material, medium and general thick plates. And also special workshop to produce thick plates that thickness is more than 300mm. we produce the steel plate include carbon and low alloy high strength steel plate, shipbuilding and offshore platform steel plate, boiler and pressure vessel steel plate, weather resistant steel plate, pipeline steel plate, alloy steel plate, automobile structure steel plate, and gas cylinder steel coil etc.

ASTM A709 carbon steel material controlled rolling is that, on the basis of adjusting the chemical composition of ASTM A709 carbon steel material, by controlling the heating temperature, rolling temperature, deformation system and other process parameters, the change law of austenite structure and the microstructure of phase transformation products are controlled, so as to achieve the purpose of refining the structure and improving the strength and toughness of ASTM A709 carbon steel material.

Tempering includes high temperature tempering, medium temperature tempering and low temperature tempering. Tempering means to reheat the ASTM A709 carbon steel material quenched steel to a certain temperature and then cool it in a certain way. Tempering can reduce or eliminate the internal stress produced by quenching, reduce the hardness and strength, and improve the ductility or toughness of steel. After ASTM A709 carbon steel material quenching, the workpiece should be tempered in time, and the required mechanical properties can be obtained through the combination of quenching and tempering.

Our company will accept the product quality objection registration record, pass it to the ASTM A709 carbon steel material production unit and relevant departments, and timely coordinate the supervision of product ASTM A709 carbon steel material quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
