The SPA-H steel section is a highly cost effective alternative

In recent years, in line with the development trend of iron and SPA-H steel section 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 SPA-H steel section 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.

The diameter of large diameter seamless steel pipe is 325mm-1220mm, and the maximum thickness that can be achieved is 200 mm. The diameter of small diameter seamless steel pipe is generally less than 89mm. The processing technology of large diameter seamless steel pipe is hot rolling or hot expanding. There are many materials for large diameter seamless steel pipe, such as SPA-H steel section, which can be processed and customized according to customer requirements. The large diameter seamless steel pipe is usually used in the chemical, petroleum, mechanical and other industries.

Structural steel alloy steel plates are unaffected by high temperatures due to their Molybdenum content, creating rock-like bodies. Combustible industries involve high-temperature procedures, where assemblies made from cheap steel can wither away. Alloy steel sheets SPA-H steel section are robust, recyclable, and have enhanced surface quality. A balance between both Steel and chromium forms DIN 15 Mo3 Alloy Steel plates imperious to oxidation and erosion, with brittle-free hardenability from Steel and Chromium. They don't age or decay, are anti-corrosion and have excellent thermal and heat conductivity.

The purpose of SPA-H steel section quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, performance, fatigue strength, toughness, and wear resistance etc. of SPA-H steel section. So as to meet the different use requirements of various mechanical parts and tools. Quenching can also help to get the ferromagnetic, corrosion resistance and other special physical and chemical properties of certain special steels.

In steel standard JIS G3106, SM570 steel owned the highest yield strength above 460 Mpa, and the tensile strength within 570-720 Mpa. For SM570 steel, the C element content is 0.18%, the Si element content is 0.55% max, the Mn element content is 1.60% max, the P element content is 0.035% max, the S element content is 0.035% max. SPA-H steel section, SM570 steel with thickness from 6mm-300mm,width from 1500mm-4000mm,length from 5000-16000mm.

Our company will accept the product quality objection registration record, pass it to the SPA-H steel section production unit and relevant departments, and timely coordinate the supervision of product SPA-H steel section quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
