The company adopts the S355MC steel, s355jr steel, s355j0 steel international advanced management system, and has passed the certification of ISO9001 quality management system, ISO14001 environmental management system and GB / T28001-2001 occupational health and safety s355mc steel, s355jr steel, s355j0 steel management system, and has realized the comprehensive integration of the three systems. In the future development path, the company will adhere to the guidance of scientific development concept, accelerate the implementation of six development strategies, namely, the main business development strategy, cost leading strategy, science and technology innovation strategy, management upgrading strategy, green steel strategy, and Harmonious Co construction strategy, promote the company's sustainable development, and build the company into the most competitive modern steel group.

SAE4340, same as UNS G43400. Tensile strength σb ≥980(100) Yield strength σs ≥835(85), used to manufacture important parts with high strength and good plasticity. After nitriding treatment, make important parts with special functional requirements, such as shafts, gears, and gears. Firmware etc. Delivery s355mc steel, s355jr steel, s355j0 steel in heat treatment (normalizing, annealing or high temperature tempering) or without heat treatment.

The s355mc steel, s355jr steel, s355j0 steel, wear-resistant steel plate has the characteristics of high strength, impact resistance, beautiful appearance, high performance, high efficiency, and high cost performance, and has a broad application prospect. The wear-resistant steel plate adopts a combination of plate and beam as a whole to carry a fully welded structure. Since the plate used is thinner, in order not to reduce the strength of the plate and reduce the deformation, try to use spot welding to form a cavity, which is the structural feature and technical key of the wear-resistant steel .

The s355mc steel, s355jr steel, s355j0 steel, heavy steel marine steel plate has the characteristics of pure steel, stable performance and good surface quality, and can be delivered at full scale. The marine steel plates are widely used in the construction of the main structure and superstructure of 10,000-ton ocean-going ships, and can also be used to manufacture the hull structure of inland ships. With the improvement of equipment level and the continuous progress of technology, heavy steel marine plate has made great progress in the production of high-strength shipbuilding steel plates, and its products are extending to the high-end market.

The quality grade of common carbon structural steel Q235 can be divided into A, B, C, D and E. Relatively, the quality of Q235A is poor and that of Q235E is the highest. Different grades of Q235 steel have different characteristics, which are mainly different from the impact temperature: Q235A does not require impact toughness test; grade Q235B is for room temperature (20℃); grade Q235C is for 0℃; grade Q235D is for - 20℃; grade Q235E is for - 40℃. The s355mc steel, s355jr steel, s355j0 steel, carbon structural steel Q235 has good combination of strength, plasticity and welding properties.
