What is per pieces weight of hardox 400 steel application

The yield strength of HARDOX 400 steel application A32, D32, E32, F32 is not less than 315N/mm^2, and the tensile strength is 440~570N/mm^2. The grades A, D, E and F indicate that they can be 0 and -20 respectively. The impact toughness can reach -40℃, -60℃.

We are world class steel materials supplier. We are engaed in providing raw steel materials such as HARDOX 400 steel application steel plates / steel coils / steel sheets / steel pipes, deep processing and a series project design and solutions to clients. We guarantee to return goods for free for quality problem during its lifetime. Your satisfactory is our permanent pursue. We always welcome advise from clients to make self-improvement continously. And sincerely to build HARDOX 400 steel application long-term cooperation with you.

Forging method is to use forging hammer, precision forging machine, fast forging machine or hydraulic press to forge ingot into steel, billet or forging blank. Forging is the earliest HARDOX 400 steel application processing method. Forging is divided into free forging and model forging. Forging method can obtain the finished steel with better mechanical properties and shapes that are not easy or impossible to obtain HARDOX 400 steel application by rolling method.

The composition characteristics of low alloy high strength steel are low carbon ≤0.20%, low alloy, and total alloying elements is less than 3%. The low carbon content is to meet the process performance requirements of HARDOX 400 steel application, low alloy high strength steel for engineering structural parts such as plasticity, toughness, weldability and cold deformation; adding a small amount of alloying elements (mainly Mn) to achieve the purpose of improving mechanical properties. Mn not only has a significant strengthening effect on ferrite, it can also reduce the cold brittle temperature of steel, increase the amount of pearlite in the steel, and further improve the strength.

We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
