A131 AH36 naval engineering steelIn terms of service, our service is a "one-stop" way of working. We have our own processing plant and pretreatment plant, pretreatment of ship steel (shot blasting, derusting, painting). Technical parameters of steel plate and profile steel surface pretreatment production line. We can also let customers enjoy our other pretreatment services, such as cutting, welding, drilling, galvanizing, etc., at the lowest cost.
A131 AH36 naval engineering steelAs the thickness and hardness of increase, the tendency to crack at the cutting edge increases. In order to prevent the from cutting cracks, preheating should be carried out before A131 AH36 naval engineering steel cutting. Special attention should be paid to preheating to make the entire interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole cannot be preheated, the partial preheating method can be used instead.When phosphorus, copper, chromium, nickel and other trace elements are added to the steel, a dense and strong adhesive protective film will be formed on the steel surface, which will prevent the corrosion from spreading and developing inward, and protect the substrate under the rust layer, so as to slow down the corrosion rate. The amorphous spinel oxide layer of about 50 μ m ~ 100 μ m thickness formed between the rust layer and the substrate is compact and has good adhesion with the substrate metal.
A131 AH36 naval engineering steel,Respect customers and treat each other sincerely. Customers are always right. Always remember that the user is the God of the enterprise, respect the customer, and accept the customer's opinion modestly is the guarantee of the long-term development of the enterprise. Adhere to this concept, so that the service and the product are the same, long-term.
