Quenched and tempered NM400 steel for vehicle
BEBON cpompany practice new development concepts, expand in an all-round way, deepen reform and innovation, speed up transformation and upgrading, become stronger, better and bigger, accelerate the implementation of BEBON Steel's NM400 steel for vehicle industrial planning, and realize the revitalization and development of enterprises.Fully implement the corporate NM400 steel for vehicle market dominant position, comprehensively promote contractual management, and promote the transition from "internal production" to "market operation”.
15Mo3 steel plate executive standard: DIN 1715515Mo3 steel plate classification: Boiler and pressure vessel steel plateApplication of 15Mo3 steel plate: 15Mo3 steel plate is mainly used to manufacture spherical storage tanks with a capacity of more than 50m3, as well as class II and III vessels such as single-layer roll welding vessels, multi-layer heat sleeve roll welding vessels, NM400 steel for vehicle multi-layer binding vessels and low-temperature pressure vessels.
Q235 steel grades cover Q235A, Q235B, Q235C and Q235D. Other than Q235A, the other three Q235 steel grades needs impact test. Charpy V-notch specimen is used for impact toughness test. The impact toughness index is Akv. Q235 steel plates are widely used because of its moderate carbon content, good comprehensive performance, good coordination of strength, plasticity and welding performance.
Laser cutting, it is a specific way of cutting NM400 steel for vehicle steel plate cutting processing, is also one of the common way of cutting its on the cutting or machining parameters, if you want to get the right number, is that you can adjust these parameters to achieve a goal, adjust a few times more to get accurate numerical right in addition, we also need to know is, the faster the cutting NM400 steel for vehicle speed, the light intensity is smaller, so, the smaller the laser penetration is, in turn, can control the penetration depth of laser.
20# seamless steel pipe chemical composition: C: 0.07-0.23, Si: 0.17-0.37, Mn: 0.35-0.65, Cr: 0.25, Ni: 0.30, Cu: 0.25. 20# seamless steel pipe mechanical properties: recommended heat treatment temperature: 910℃, tensile strength: 410 MPa, yield strength: 245 MPa, elongation: 25%, impact energy is not required. 20# seamless steel pipe hardness is higher than 10# seamless steel pipe. NM400 steel for vehicle, 20# seamless steel pipe has good weldability, no temper brittleness, and its machinability can be improved by water quenching. 20# seamless steel pipe can be used to make welded components, as well as parts with small load after forging, hot stamping and cutting.
First of all, we should establish a correct concept of after-sales service. Service concept is an important part of corporate culture and a long-term enterprise value concept. Our company's after-sales service embodies the concept of "customer first, sincere service for customers". As long as we are in the "sincere service for users" under the guidance of the idea, I believe we will get rich returns.
