China sa573 grade 70 structural quality carbon steel plate steel supplier factory

In recent years, in line with the development trend of iron and sa573 grade 70 structural quality carbon steel plate steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which sa573 grade 70 structural quality carbon steel plate are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

In 1045 steel plate, the ‘10’ means a basic carbon steel and ‘45’ designates the approximate carbon content. 1045 steel is included in the ASTM 830 (A830) family of specifications. A830 Grade 1045 hot rolled steel plate can be cut to various shapes, hammer forged and heat treated. 1sa573 grade 70 structural quality carbon steel plate product is mostly used where greater strength is required than lower carbon steels. Welcome to contact us for hot rolled plates stock price.

The mechanical properties of 30CrMo steel are as follows: tensile strength 930 MPa, yield strength 785 MPa, elongation after fracture 12%, impact absorption energy 63 J. sa573 grade 70 structural quality carbon steel plate, 30CrMo steel has high strength and toughness. When the temperature is lower than 500℃, 30CrMo steel has good high-temperature strength, good machinability, medium cold bending plasticity, high hardenability and good welding performance. 30CrMo steel is generally used in quenched and tempered condition.

Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized sa573 grade 70 structural quality carbon steel plate are higher than that of annealed sa573 grade 70 structural quality carbon steel plate, but the elimination of internal stress is not as good as annealing. The normalizing operation of sa573 grade 70 structural quality carbon steel plate is simple, the cost is low, the productivity is high, and it is widely used in actual production.
