HG785D steel plate performance index parameters

HG785D is a kind of high-strength welded structural steel, where "785" means that the tensile strength of the steel plate is about 785Mpa, and "D" means the quality grade of the steel plate.

This kind of steel plate has high yield strength and tensile strength, and is often used in large steel structural parts such as coal mining machinery and mining machinery, such as mining hydraulic supports, cranes, etc.

The chemical composition of HG785D steel plate is as follows: C content ≤ 0.12, Si content ≤ 0.40, Mn content ≤ 1.8, P content ≤ 0.025, S content ≤ 0.015, Ni content ≤ 0.75, Cr content ≤ 0.70, Mo content ≤ 0.50, Nb content ≤ 0.060, Ti content ≤ 0.020, B content ≤ 0.0020.

The mechanical performance parameters of HG785D steel plate are: yield strength ≥685Mpa, tensile strength ≥785Mpa, elongation ≥15%, impact temperature -20°C, impact energy 47J.

HG785D steel plate is a high-strength steel plate that is widely used in various manufacturing fields such as pressure vessels, coal mining machinery, mining machinery, and large steel structures.

In terms of equipment manufacturing, this kind of steel plate is often used to manufacture equipment with heavy weight and complex structure, such as hydraulic supports for mining, cranes, chemical equipment, ship equipment, etc.
