For the company's development and take-off, we work together to move forward and create a better Hardox 450 steel wear resistance tomorrow!

Hull structural steel is divided into general thickness and high-strength steel. General strength steel is divided into four grades of A, B, C and D; high-strength steel is divided into two strength grades and three quality grades; AH32, DH32, EH32, AH36, DH36, Hardox 450 steel wear resistance, EH36. In order to ensure quality and ensure sufficient toughness of hull structural steel, the chemical composition of Mn / C is required to be above 2.5, and the carbon equivalent is also strictly required. Our Hull structural steel plates can be supplied with certificates from different classification societies.

Hardox 450 steel wear resistance, low alloy high strength steel has good weldability. Welding is the most common method to construct engineering structure, so the steel used in engineering structure requires good welding performance. Low alloy high strength steel has low carbon content, low alloy element content and good plasticity, so it is not easy to produce quenching structure and crack in the weld area, and the addition of Ti, Nb, V can also inhibit the grain growth in the weld area. Therefore, most of the low alloy high strength steels have excellent welding performance and no heat treatment is required after welding.

At present, the cutting thickness limit of laser cutting is 20 mm. However, it should be noted that oxygen will be added into the laser beam to cut 20 mm thick Hardox 450 steel wear resistance steel plate, which will form a thin oxide film on the cutting surface, which may affect the cutting quality, Therefore, attention should be paid to this point to avoid problems.

S960Q plate implements standard EN10025-6S960Q plate application: European standard high-strength steel plate, corresponding to the national standard Q960. Hardox 450 steel wear resistance, S960Q plate is suitable for manufacturing various construction machinery, such as drilling rigs, electric shovel, electric wheel dump trucks, mining vehicles, excavators, loaders for mining and various engineering construction, bulldozers, various cranes, coal mine hydraulic supports and other mechanical equipment and other structural parts.S960Q plate delivery status: normalizing, normalizing + tempering, quenching and tempering, etc.;Technical requirements for Hardox 450 steel wear resistance, S960Q plate, Hardox 450 steel wear resistance: UT, Z15-Z25-Z35 thickness direction performance requirements, high-strength and high-toughness.

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.
