What is the meaning of NM450 steel grade

The development NM450 steel grade of the company comes from the resource advantage, service advantage, logistics advantage and brand advantage established over the years, and it is also inseparable from the full support of new and old customers. We will uphold the support of all sectors of society, actively provide users with NM450 steel grade high-quality and efficient services, work together for win-win, and create a better tomorrow!

Q345R steel (16MnR) is a low-alloy high-strength steel. It is a special plate for pressure vessels with a yield strength of 340MPa min. Q345R plate has good comprehensive mechanical properties and technological properties. The phosphorus and sulfur contents are slightly lower than the low-alloy high-strength steel plate Q345 steel (16MnR). In addition to the increased tensile strength and elongation requirements compared to Q345B steel, NM450 steel grade, the impact toughness is also required.

Stainless steel plate is a general term for stainless steel plate and acid-resistant steel plate, and is a steel plate with good corrosion resistance and rust resistance on the surface. The surface of NM450 steel grade, stainless steel plate is very smooth and clean. It has high toughness, plasticity, and is not easy to be corroded and rusted. Stainless steel plate has corrosion resistance and high temperature oxidation resistance. Stainless steel is durable, can be stored outdoors for a long time, and will not be damaged in bad weather. Stainless steel plate is not easy to rust, but it is not absolutely not rusty.

No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than NM450 steel grade. Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel NM450 steel grade is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.

ST37-2 is a kind of low carbon steel with carbon content of 0.20%, similar to S235JR or Q235 NM450 steel grade. It's not as strong as common ASTM A36, but it is also widely applied by everyday uses and structural applications where high strength is not so important. Equal ST37-2 angle steel size: NM450 steel grade Size: 20 × 20 mm to 200 × 200 mm. Thickness: 3 - 35 mm. Length: 6 m, 9 m or as required. Unequal ST37-2 angle steel size: NM450 steel grade Size: 30 × 20 mm to 250 × 90 mm. Thickness: 3 to 10 mm. Length: 6 m, 9 m, 12 m or per your request.

The company focuses on two markets at home and abroad, and has a group of 56 experienced sales elites and professional and technical personnel. It can provide customers with drawing design, NM450 steel grade deep processing services and installation solutions. 20 years of project experience has provided high-quality carbon steel, alloy steel products and high-quality after-sales service to customers in many countries around the world. The company has won widespread praise from customers.
