p265gh steel plate quality and thickness range

Quenching is a heat treatment process in which steel parts are heated to above the critical temperature, and after proper heat preservation, the parts are quickly cooled to room temperature in water or oil, so that martensite transformation occurs. The hardness of the quenched P265GH steel plate increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of p265gh steel plate during tempering, while tempering determines the performance and life of the workpiece.

Compared with other fast-moving consumer goods, steel consumption is obviously different, with a wide range of use and a long service life. Therefore, the quality and service of steel materials are particularly important. Service is always one of our top concerns, especially after-sales service. We have mature after-sales service team, and can help you solve problems professionally during application of the steel materials.

SA387 Gr.12 Cl.2 steel has the ability to prevent hydrogen embrittlement, hydrogen corrosion, hydrogen stripping, and sulfide corrosion in a medium temperature (350 - 480℃) hydrogen environment. At the same time, p265gh steel plate, SA387 Gr.12 Cl.2 has good low temper embrittlement and is widely used in fertilizers, petrochemicals, and the manufacture of thermal power plant equipment, such as ammonia synthesis reactor, coal gasifier, shift furnace and hydrogenation reactor.

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 p265gh 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 p265gh steel plate etc. steel is strictly controlled.
