What is p235gh carbon steel ASTM equivalent

Advantages of P235GH carbon steel: 1. Steel purity: Wugang can produce high purity molten steel with P 0.010%, S 0.005%, N70ppm, O15ppm, H2ppm, and 20ppm total inclusions in the steel. 2. Good toughness and weldability. 3. The heat treatment technology: normalizing, quenching, tempering, tempering and other heat treatment processing can be carried out on the steel plate as required. 4. Significantly improve the plasticity and impact toughness of steel, and improve the anisotropy of steel.

The main reference for structural design of steel structure engineering is the static and dynamic characteristics of the steel used under various actions, such as elasticity, plasticity, strength, toughness, fatigue and other mechanical properties. Therefore, the p235gh carbon steel and so on steel used in the construction of steel structure engineering will limit its strength, plasticity, impact toughness and weldability. Steel structure engineering requires high tensile strength and yield point of steel. High yield point can reduce the cross-section of the component, so as to reduce the weight, save steel and reduce the cost. High tensile strength can increase the safety of the structure.

According to the data of the National Bureau of statistics, from January to February, the output of pig iron, crude steel and steel (excluding repetitive materials) were 132.34 million tons, 154.7 million tons and 167.13 million tons, respectively, up 3.1%, 3.1% and 3.4% year on year; the daily output of p235gh carbon steel, crude steel was 2.5783 million tons, down 5.15% year on year.

p235gh carbon steel product plate production process:Raw materials (scrap steel, pig iron and molten iron) → electric furnace (100 tons electric arc furnace smelting) → converter → LF furnace molten steel refining treatment → VD or VOD furnace molten steel vacuum treatment → die casting (various key die casting lines) or continuous casting (large Slab caster) (50 tons of slab electroslag furnace for remelting a steel ingot) → heating (continuous furnace and soaking furnace) → steel plate rolling (4100 and 4200mm rolling mills) → steel plate heat treatment (normalizing and tempering) Quality) →Steel plate cutting inspection→Inspection
