Hot/cold rolled welding of nm400 steel sheet

ASTM A36 and other alloys can be formed into various shapes for building welding of NM400 steel sheet construction. These include steel tubes; wide flanges, or W shapes; American Standard I-beams, or S shapes; structural tees, or T shapes; channels, or C shapes; angles, or L shapes; welding of NM400 steel sheet steel plates; and steel bars. Steel tubes are usually used as columns.

At the same time, the company operates a variety of products of related iron and welding of NM400 steel sheet steel enterprises. Annual sales of steel 3.6 million tons, standing stock of 400000 tons, has developed more than 10000 users. The company has a first-class marketing service system, strong storage and transportation capacity and supporting supply, cutting distribution capacity, and gradually build it into an important marketing channel. The company has obtained welding of NM400 steel sheet ISO9001:2000 quality system certification, A-level credit unit of the people's Bank of China, and is an excellent supplier of many large state-owned enterprises.

Preheating cutting: The most effective way to prevent steel plate cutting cracks is to preheat before cutting. Before flame cutting, the steel plate is usually preheated, and the preheating temperature mainly depends on the quality level and thickness of the steel plate. The preheating method can be carried out with flame burner, electronic heating pad, or heating furnace. In order to determine the preheating effect of the steel plate, the required temperature should be tested at the heating point.

Stainless steel plate and other plates are like smelting, refining, casting, rolling, hot rolling and cold rolling is the final process steps in the manufacture of stainless steel. At present most of the world's welding of NM400 steel sheet stainless steel factory use the AOD furnace furnace ldpe-g-nvp stainless steel production, its production accounted for about 70% of the world's stainless steel output, a VOD furnace a converter three-step method is used to produce stainless steel, its production accounted for about 20% of the world's welding of NM400 steel sheet stainless steel production, production of stainless steel with other methods, its production accounted for about 10% of the world's production of stainless steel.

The company adopts one-to-one fast service and has formed a professional after-sales service team to deal with various problems reflected by customers as soon as possible. At the same time, a traceable product traceability system has been established. It has always been placed at an important core position to resolve customer worries. Our steel welding of NM400 steel sheet products are always committed to “quality issues, life-long replacement”, which is the embodiment of our comprehensive service.
