The normalizing technology of nm400 steel grade

The NM400 steel grade plate products have passed the EU CE certification, and have been recognized by China, France, the United States, the United Kingdom, Germany, Italy, Japan, South Korea and other eight classification societies for high-strength ship plates. The steel strand products have passed the United States (PTI) certification. The NM400 steel grade products enjoy a high reputation in the domestic and foreign markets. The products are applied to national key projects and sold to 37 countries and regions such as EU, Middle East, Southeast Asia and America.

The main steel plates for oil and gas pipelines are X42, X46, X52 (L360), X56 (L390), X60 (L420), X65 (L460), X70, X80. The specification range of steel plate used by the company for oil and gas pipelines: thickness 8mm-60mm. It can produce additional flaw detection requirements and Z15-Z35 tear resistance (thickness direction performance) steel plates NM400 steel grade, and can also provide Z-direction performance steel plates according to ASTM A770 and other standards.

Wear resistant plate is composed of two parts, namely carbon steel plate and alloy wear-resistant layer. Under normal conditions, the thickness of the NM400 steel grade alloy wear-resistant layer of the wear-resistant plate is 1 / 3-1 / 2 of the total thickness. When working, the matrix provides the strength, toughness, plasticity and other comprehensive properties to resist external forces, and the alloy wear-resistant layer provides the NM400 steel grade wear-resistant property to meet the requirements of specific working conditions.

Now many manufacturers will use CNC equipment to complete the steel plate cutting processing, this processing method is also gradually increasing, but if you want to make the processing effect meet the specifications and standards, the control requirements of operation technology are also relatively high. Now there are many kinds of steel plate cutting, during the actual processing, it is necessary to select the appropriate processing method according to the cutting requirements of steel plate, so as to achieve the ideal processing effect for NM400 steel grade.

NM400 steel grade, A572 Grade 50 steel with the thickness range is 1.2-600mm, the width range is 1220-4200mm, and the length range is 5000-18000mm. Also note that the A572 Grade 50 steel coil thickness should not exceed 25 mm. For A572 Grade 50 steel, the C element content is 0.23%, the Si element content is 0.4% max, the Mn element content is 1.35% max, the P element content is 0.004% max, the S element content is 0.05% max, the V element content is 0.06%, the Ni element content is 0.015%, the Co element content is 0.05%.
