EN steel grade S355K2 material plain carbon steel

EN10028-2 P295GH plate with elevated temperature property gives optimum performance for pressurized products that must support a creep limit greater than 155N/mm2 at 400ºC. EN steel grade S355K2 material, P295GH plate is a normalized steel and has excellent welding characteristics. P295GH plates and sheets are used worldwide by fabricators serving the oil and gas industry and can be found in heat exchangers, weldable pressure vessels and boilers and pipework.

EN steel grade S355K2 material, low alloy high strength steel has good weldability. Welding is the most common method to construct engineering structure, so the steel used in engineering structure requires good welding performance. Low alloy high strength steel has low carbon content, low alloy element content and good plasticity, so it is not easy to produce quenching structure and crack in the weld area, and the addition of Ti, Nb, V can also inhibit the grain growth in the weld area. Therefore, most of the low alloy high strength steels have excellent welding performance and no heat treatment is required after welding.

Weathering steel generally adopts the process route of fine material into the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire)-controlled rolling and cooling. The scrap steel is added into the furnace together with the charge, and smelted according to the conventional process. After the EN steel grade S355K2 material steel is tapped, deoxidizers and alloys are added. After the molten steel is treated with argon blowing, the molten steel is cast. By adding rare earth elements to the steel, the EN steel grade S355K2 material weathering steel is purified and the content of inclusions is greatly reduced.
