What is grade sa573 grade 70 structural quality carbon steell?

DIN 34CrMo4 steel Strength, high hardenability, toughness, and quenching small deformation, high strength and creep rupture strength at high temperatures. Requirements for the manufacture of higher intensity than the 35CrMo steel sa573 grade 70 structural quality carbon steel and tempered forging greater cross-section, such as a large locomotive traction gears, supercharger drive gear, pressure vessels, gear, rear axle, greatly affected by load and spring clip link It can also be used to 2000m deep oil drill pipe joints and fishing tools, and sa573 grade 70 structural quality carbon steel can be used bending machine mold, etc.

SM490A steel plate is a low-alloy high-strength steel. It is a structural steel produced in accordance with Japanese standard JIS G3106. Its strength σb is 490MPa. It is mainly used for buildings, bridges, ships, rail vehicles, petroleum storage tanks, containers and other buildings that require advanced weldability. sa573 grade 70 structural quality carbon steel, JIS SM490A steel sheet delivery status: steel plates with a thickness of <80mm, the delivery state is hot-rolled; steel plates with a thickness of ≥80mm, the delivery state is normalized condition.

Shipbuilding steel plates have always been the key products of our company, and it is sold well in many countries and regions around the world. The thinnest certifiable thickness of our shipbuilding steel plates is up to 3mm. We cooperate with classification societies to certify the shipbuilding steel sa573 grade 70 structural quality carbon steel and issue EN10204 3.2 material test certificate. According to the certificate number, the customer can verify the source of the shipbuilding steel plates with the corresponding classification society near them.

The alloying principle of low alloy high strength steel plate mainly uses solid volume strengthening, fine grain strengthening and precipitation strengthening produced by alloy elements to improve the strength of low alloy high strength steel plate, sa573 grade 70 structural quality carbon steel. At the same time, the effect of fine grain strengthening on the reduction of ductile brittle transition temperature of low alloy high strength steel platel is used to offset the adverse effect of carbon nitride precipitation strengthening on the rise of ductile brittle transition temperature of steel, so that low alloy high strength steel plate can obtain high strength while maintaining good low temperature performance.

sa573 grade 70 structural quality carbon steel, SS400 steel is one of the most commonly used hot rolled general structural steel. SS400 steel’s mechanical properties is yield strength more than 225-235MPa, tensile strength 360-510Mpa and 340-470Mpa. For SS400 steel, the C element content is 0.2% max, the Mn element content is 1.40% max, the P element content is 0.045% max, the S element content is 0.045% max.
