What is the difference between 1018 and nm500 steel equivalent grades steel?

Since it was established in 2000. Based on the domestic rich NM500 steel equivalent grades product resources and the great steel demand of the international market, our NM500 steel equivalent grades service has already spread many countries in Europe , America, Southeast Asia, Middle East, South America, Africa, etc, and we have won an outstanding reputation for its professional exporting steel products

With the development of remote oil and gas fields, polar oil and gas fields, offshore oil and gas fields and acid oil and gas fields, oil and gas pipeline engineering is facing challenges of high-pressure transmission and harsh environment such as low temperature, large displacement, deep sea and acid medium. In order to ensure the enthusiasm and safety of pipeline construction and operation, the basic requirements and development trend of NM500 steel equivalent grades, pipeline steel are high strength, high toughness, large deformation, thick wall, high corrosion and good weldability.

Grade Q420 steel has high strength, especially in the normalizing or normalizing and tempering state. NM500 steel equivalent grades, Q420 steel has high comprehensive mechanical properties. Q420 steel is mainly used for large ships, bridges, power station equipment, medium and high pressure boilers, high pressure vessels, rolling stock, hoisting machinery, mining machinery and other large welded structural parts. Grade Q460 steel, with high strength, has high comprehensive mechanical properties in normalizing, normalizing and tempering or quenching and tempering states. The quality grades are C, D, E. Q460 steel is used in various large engineering structures and light structures requiring high strength and heavy load.

Vanadium element (V element) can refine grains in ordinary low carbon alloy steel, improve the strength and yield ratio and low temperature characteristics after normalizing, and improve the welding performance of steel, NM500 steel equivalent grades included. Vanadium element (V element) is often used in combination with manganese, chromium, molybdenum, tungsten and other elements in structural steel because of its low hardenability under general heat treatment conditions. Vanadium in quenched and tempered steel is mainly to improve the strength and yield ratio of steel, refine the grain size, and pick up the overheating sensitivity.
