Grade EH36 marine steel: E is the quality grade E, H is the high-strength building material, 36 is the maximum compression, and Z is the Z-direction stretching. Grade EH36 structural steel for high-strength hull refers to the steel used for manufacturing the hull structure produced according to the requirements of the classification society. Our company mainly supply Grade EH36 hot rolled plate, BV DH36 hull shipbuilding plate, Grade EH36 angle steel bars and steel sections.
Over the years, the company has trained a number of professional sales talents, enriched the concept of various marketing and customer service, and strengthened the business strength of the company. Now the company's business BV DH36 hull shipbuilding plate department, marketing department and information department constitute the market development network; the finance department, personnel department, logistics department, shipping department, document department and BV DH36 hull shipbuilding plate after-sales service department constitute the service customer network.
No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than BV DH36 hull shipbuilding plate. Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel BV DH36 hull shipbuilding plate is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.
The chromium plays an important role in BV DH36 hull shipbuilding plate, Chromium Molybdenum steel. The chromium can form a dense oxide film with strong adhesion on the surface of the steel plate, so as to prevent the internal metal from further oxidation or corrosion. The higher the chromium content in the steel plate, the denser the oxide film, and the better the oxidation resistance and corrosion resistance of the steel plate.
The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
