The way to improve dimension qualification rate of NM400 material meaning

The ASTM A572 NM400 material meaning specification refers to high-strength low-alloy steel plates used in structural buildings. Among the five steel grades 42, 50, 55, 60 and 65, grade 50 is the most common in applications requiring higher strength and lighter weight. One of the NM400 material meaning steels, the steel plate of this brand other than ordinary carbon steel is used, so that the steel structure has the same steel strength, but the weight is lighter.

Weather-resistant steel plate has excellent hot-rolled steel plate with resistance to sulfuric acid dew point corrosion. Its superior sulfuric acid dew point corrosion resistance and very high cost performance are the best materials NM400 material meaning that can completely replace stainless steel and surpass stainless steel (in terms of sulfuric acid dew point corrosion resistance). ND steel has great economic significance and is in line with today's high efficiency, long life and energy saving.

Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while NM400 material meaning steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of NM400 material meaning steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.
