Grade nm300 steel equivalent grades for welded boilers

The company produces seamless steel pipes such as GB, ASTM, etc. all year round, including low and medium pressure boiler steel pipes, high pressure boiler steel pipes, nm300 steel equivalent grades seamless steel pipes for ships and petroleum cracking nm300 steel equivalent grades steel pipes, Seamless steel pipe, oil sleeve steel pipe, pipeline steel pipe, hollow sucker rod, common fluid steel pipe, structural pipe, kauden steel pipe, seawater corrosion-resistant titanium pipe and imported alloy steel pipe are used for high-pressure fertilizer equipment. The products are widely used in petroleum, chemical, electric, boiler, ship, machinery and other industries, and have been sold all over the country. Many nm300 steel equivalent grades products have been exported to the Middle East, India, Southeast Asia and Europe and America.

1.4306 characteristics and applications: X2CrNi189 stainless steel, German DIN standard stainless steel. It is equivalent to 00Cr19Ni10 in my country and SUS304L in Japan. The difference from 304L stainless steel is only in terms of nitrogen content and nickel content. The former is 0.04 and 10.1, and the latter is 0.06 and 8.3. This material distinction is common in the Swedish Avista series.

37SiMn2MoV steel is high-grade quenched and tempered steel. nm300 steel equivalent grades, 37SiMn2MoV steel has excellent comprehensive mechanical properties, good heat treatment process, good hardenability, low sensitivity to quenching crack, high resistance to tempering, very low temper brittleness, good high temperature strength and low temperature toughness. Chemical composition of 37SiMn2MoV steel: C: 0.33-0.39, Si: 0.60-0.90, Mn: 1.60-1.90, Mo 0.40-0.50, V: 0.05-0.12. After quenching and tempering, 37SiMn2MoV steel is usually used to manufacture heavy load and large section important parts.

First to determine the welding methods, such as hand arc welding, submerged arc welding and tungsten argon arc welding, melting polar gas shielded welding machine, and so on are very many different kinds of nm300 steel equivalent grades welding method, can only be chosen according to specific situation, determine the welding method, and make welding process parameters, different kinds of welding process parameters, such as manual welding mainly includes: electrode model (or brand) diameter, current, voltage, welding power source type and polarity connection, welding layer number, number, inspection method, etc.
