What is EN 10025-6 high strength steel S620Q material

In recent years, in line with the development trend of iron and EN 10025-6 high strength steel S620Q steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which EN 10025-6 high strength steel S620Q are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

Q355NH material is a Chinese steel grade to GB/T 4171-2008 atmospheric corrosion resisting structural steel. There are five steel levels under Q355NH: Grade A, B, C, D, and E. Q355NH structural steel sheet is mainly used in vehicles, containers, construction, towers or other structural parts and other structures. It has good resistance to atmospheric corrosion. We supply EN 10025-6 high strength steel S620Q, Q355NH steel plates thickness less than 120mm.

The excellent properties of wear resistant steel plate meet the strict requirements of high strength, high wear resistance, stability, straightness and surface quality. The combination of high hardness, high strength and excellent impact toughness makes EN 10025-6 high strength steel S620Q plate become an ideal material for a wide range of applications. The production thickness of wear resistant steel plate is generally between 8-100mm.

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 EN 10025-6 high strength steel S620Q increases sharply. Quenching is to prepare the organization for adjusting and improving the performance of EN 10025-6 high strength steel S620Q during tempering, while tempering determines the performance and life of the workpiece.

EN 10025-6 high strength steel S620Q, 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.

In addition to quality assurance, service is also important for the competition of steel suppliers. All the after-sales service personnel of the company have received professional training and assessment. The steel products supplied by our company enjoy the life-long quality problem replacement service.
