ASTM A217 stainless steel castings in the product form of valves, flanges, fittings and other pressure-containing parts. ASTM A217/A217M covers one grade of martensitic stainless steel and nine grades of ferritic alloy steel which are primarily utilized in high-temperature and corrosive service. It includes C-Mo alloy steel: Grade WC1; Cr-Mo alloy steel: Grade WC4, WC5, A514 Gr E quenched and tempered steel, Grade WC6, WC9, WC11, C5, C12; Cr-Mo-V alloy steel: Grade C12A; and Chromium Steel: Grade CA15.
At the same time, the company operates a variety of products of related iron and A514 Gr E quenched and tempered steel steel enterprises. Annual sales of steel 3.6 million tons, standing stock of 400000 tons, has developed more than 10000 users. The company has a first-class marketing service system, strong storage and transportation capacity and supporting supply, cutting distribution capacity, and gradually build it into an important marketing channel. The company has obtained A514 Gr E quenched and tempered steel ISO9001:2000 quality system certification, A-level credit unit of the people's Bank of China, and is an excellent supplier of many large state-owned enterprises.
Laser cutting, it is a specific way of cutting A514 Gr E quenched and tempered steel steel plate cutting processing, is also one of the common way of cutting its on the cutting or machining parameters, if you want to get the right number, is that you can adjust these parameters to achieve a goal, adjust a few times more to get accurate numerical right in addition, we also need to know is, the faster the cutting A514 Gr E quenched and tempered steel speed, the light intensity is smaller, so, the smaller the laser penetration is, in turn, can control the penetration depth of laser.
When phosphorus, copper, chromium, nickel and other trace elements are added to the steel, A514 Gr E quenched and tempered 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.
Adhere to the spirit of quality first and user foremost, carry out maintenance and other work according to the requirements of the buyer's contract, and ensure that the engineering project and product after-sales play their application effectiveness. Our company guarantees to carry out self inspection and self supervision according to the quality management policy proposed by our company, and deliver a high-grade, perfect and excellent system engineering to users.
