The heat treatment knowledge of mechanical properties of nm550

The company specializes in producing high-strength low-temperature resistant low alloy plates Q345C, Q345D, Q345E, SM400, mechanical properties of NM550, SM490, S355J2 + N;bridge plates Q345qC / qD / qE, Q370qE high-strength structural plates, etc. Z-direction performance (Z15, Z25, Z35). Above materials have high yield strength, high tensile strength, Brinell hardness, and Rockwell hardness; and low temperature resistance, they also can be maintained at high temperatures of -60 ℃.

The boiler steel plate has small strain aging sensitivity, especially in the corresponding working temperature range, a certain value of aging impact energy must be guaranteed;The boiler steel plate has low notch sensitivity, which can prevent steel from cracking in welding, opening, and local stress concentration areas;The mechanical properties of NM550, boiler steel plate has good welding performance;The mechanical properties of NM550, boiler steel plate has a good microstructure, white spots and cracks are not allowed.

The blanking of the structural steel plate is first to find 90 degrees, and then use a tape measure and a powder line to draw the cutting range. According to the thickness of the carbon steel plate plus the cutting allowance, drilling is required. For the deep processing of mechanical properties of NM550 structural steel sections or profiles: First use a square ruler or a curved ruler to find 90 degrees, and then use a square ruler or a ruler to cut the line and add the cutting margin to the hole.

We have our own factory, including the production and manufacturing of steel pipes, with a special mechanical properties of NM550 steel pipe manufacturer and storage warehouse. Welcome to visit our factory, we will provide customers with high quality products that meet the requirements. And has the perfect mechanical properties of NM550 after-sale service guarantee system, lets the customer save the worry and the labor.

After-sales service is an important part of measuring a product good or not. After sales service can't be ignored. Good service can really make consumers feel relieved. We have always done a good job in after-sales service, so as to bring consumers a better reference when purchasing and a better experience during use of our steel materials. We will call back and follow up the performance of our steel products regularly.
