Laser cutting welding process of hardox 400
Our after sales department is an very important part of our department structures. After the customer receive steel materials, our after sales department will follow up regularly and solve problems for them in time if they have the needs. We romise to return the goods for free for its lifetime if it is quality of the steel material itself. Meanwhile, if you have any advice or complaints, also welcome to feed back to our after sales department, and we are trying to give better service to you.
Pipeline steel plate API 5L Gr.B, welding process of HARDOX 400, X42, X46, X52, X56, X60, X65, X70, X80 is a key steel material for manufacturing straight-seam submerged arc welded pipe for high-pressure long-distance natural gas pipeline. X80 pipeline steel is currently the highest-grade pipeline steel in engineering application in the world. The our company produced X80 pipeline steel plates are successfully used in natural gas pipeline project with the largest wall thickness and diameter.
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 welding process of HARDOX 400, boiler steel plate has good welding performance;The welding process of HARDOX 400, boiler steel plate has a good microstructure, white spots and cracks are not allowed.
Heat treatment process: heat treatment refers to a kind of process operation in which the metal or alloy can change the internal structure through certain heating, heat preservation and cooling methods in the solid range to obtain the required performance. welding process of HARDOX 400 Heat treatment process refers to the ability to change the microstructure and properties of welding process of HARDOX 400 after heat treatment, including hardenability, hardenability, temper brittleness, etc.
The high strength welding process of HARDOX 400 low alloy steel, which is shorten as HSLA steel, is one of our main products. We have professional team to serve you. For any demands or questions about HSLA steel, for example, ASTM A572 grade 50 chemical composition, difference between S355JR and S355J2, mechanical properties of welding process of HARDOX 400 ST52 steel, Q345B tensile strength, Q345D steel ASTM equivalent, HSLA steel price etc. , please do not hesitate to contact us and consult.
