13CrMo4-5 steel plate delivery status and production process is strictly produced according to EN10028-2 standard. Delivery status: normalizing + tempering, tempering. The 13CrMo4-5 alloy plates thickness below 100mm, it is normalizing + tempering; Thickness 100mm-150mm, the plate is delivered in normalizing + tempering or quenched and tempered;150mm-250mm is delivered in tempered condition. The requirements for flaw detection levels, and Z-direction functional requirements can also be added.
The BBNSTEEL company has the first-class qualification for steel structure professional contracting, integrating production, design and installation, and can undertake various steel structure projects. The product has a wide surface, flat and smooth surface, and neat trimming. It has users in more than 10 provinces and cities in China and is exported to the United States, Canada, Japan, Europe, Southeast Asia and other countries and regions.
We do sand blasting and shop primer for various A588 grade A high strength steel steel plates such as carbon steel plates, high strength low alloy steel plates, shipbuilding steel plates, etc. before delivery, so as to protect the steel plates from going rust during transportation. Our sand blasting standard is SA2.5, and shop primer A588 grade A high strength steel thickness is 20μm or so. Our shop primer has been certified by ABS, LR, BV etc. authorities.
The addition of Ca element in steel such as A588 grade A high strength steel can refine grain size, partly desulphurize and change the composition, quantity and morphology of non-metallic inclusions. It is similar to that of adding rare earth in steel. It can improve the corrosion resistance, wear resistance, high temperature and low temperature resistance of steel, improve the impact toughness, fatigue strength, plasticity and welding performance of the steel, and increase the cold heading, shock resistance, hardness and contact endurance strength of the steel.
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.
