Production growth of EN1522 FB7 armor steel plate mill slows down

location: home > news >Production growth of EN1522 FB7 armor steel plate mill slows down

Phosphorus element (P element) is brought into steel by ore. Generally speaking, phosphorus is also harmful element. Although phosphorus can increase the strength and hardness of EN1522 FB7 armor steel plate etc. steel, it also causes the decrease of plasticity and impact toughness. Especially at low temperature, it makes steel significantly brittle, which is called "cold brittleness". The higher the phosphorus content is, the greater the cold brittleness is. Therefore, the phosphorus content in EN1522 FB7 armor steel plate etc. steel is strictly controlled.

EN1522 FB7 armor steel plate, 30CrNi3MoV high strength steel is mainly used as structural material for key parts of a major weapon model. Chemical composition of 30CrNi3MoV (675): C: 0.26-0.32, Si: 0.15-0.35, Mn: 0.30-0.50, P: ≤ 0.015, S: ≤ 0.010, Cr: 0.60-1.00, Ni: 2.80-3.20, Mo: 0.40-0.50, Re: 0.06-0.13, V: 0.06-0.013.

The results of adopting two-level EN1522 FB7 armor steel plate service system and implementing standardized management are mainly reflected in the formation of vigorous work style such as quick response and quick action. Our company's customer service center stipulates that employees must be accurate and quick in technical support and EN1522 FB7 armor steel plate after-sales service. Through the formation of this fast, agile, vigorous style, to provide users with satisfactory service.

The EN1522 FB7 armor steel plate processing performance is good. Due to the uniform control of steel plate performance, excellent performance coordination and good toughness guarantee, the steel plate bending processing, drilling, cutting and other mechanical processing properties are excellent. In addition, the surface of the EN1522 FB7 armor steel plate steel plate is smooth and beautiful by inhibiting and removing oxide scale from slab heating to rolling process and heat treatment in furnace without oxidation atmosphere.
