What is steel grade spa-h used for

The company was established in 2000, covering an area of more than 4,500 acres. It has fixed assets of 200 million yuan, and employs more than 1,200 people. It has now formed coking, sintering, white ash, pellets, ironmaking, steel grade spa-h steelmaking, steel rolling, oxygen production, gas and waste heat The complete circular economy industrial chain including power generation, comprehensive utilization of slag, soot and dust treatment, sewage treatment and recycling, etc. It mainly produces hot-rolled steel plates and steel grade spa-h carbon structural steels, high-quality carbon structural steels, low-alloy high-strength steels, medium and wide-band steels for cold-rolled stamping, and hot-rolled coils.

steel grade spa-h, 45# steel is carbon steel, belonging to high strength medium carbon quenched and tempered steel, with carbon content of 0.45%, so it is called 45# steel. 45# steel does not contain specially included alloy elements. steel grade spa-h, 45# steel is one of the most widely used high-quality structural steel. 45# steel is suitable for manufacturing high strength moving parts, such as air compressor, piston of pump, impeller of steam turbine, rolling shaft, connecting rod, worm, rack, gear and pin in heavy and general machinery.

The main metal material steel grade spa-h used to make the boiler is steel. The main boiler body is composed of the parts which bear static load under normal temperature and the parts which bear high pressure and high temperature. The former part can be made of general structural steel, while the latter part must be made of steel with special properties, i.e. boiler steel. Boiler steel is required to have good high temperature resistance, stable structure, machining performance, etc. properties.

After hot extrusion, the grains of the alloy wear-resistant steel plate are significantly refined, dendrites and network structures are broken, and the grain size and the distribution of precipitated phases in the alloy are more uniform to generate Al2Y and Al3Y phases distributed within and along the grain boundaries , The hardness is significantly improved, the mechanical properties are significantly improved, the deformation strengthening effect is more significant, and the corrosion resistance of the steel grade spa-h, alloy wear-resistant steel plate is significantly improved.

S355J2 steel plate yield strength Rp0.2≥265mpa, tensile strength RM: 450-680mpa, elongation a≥12%, impact energy Kv2≥27J, tensile area shrinkage Z≥35% in thickness direction. steel grade spa-h, S355J2 steel plate has good internal quality, high density and stable performance.Meaning of S355J2-Z35: J2 requires negative 20 degree impact, and Z35 is the Z-direction performance of S355J2 steel plate.The meaning of S355J2 + N-Z35: J2 requires negative 20 degree impact, N means normalizing rolling rather than normalizing. Z35 is the Z-direction performance of S355J2 steel plate, steel grade spa-h.

The company always adheres to the quality policy of "Quality First, Continuous Improvement, Customer Satisfaction" and the business philosophy of "Continuous Progress, Pursuing Excellence", as always, we look forward to cooperating with you to create a new situation for common development.Steel products steel grade spa-h price concessions, rich industry experience, complete varieties.
