What is 630/17-4PH/1.4542 Stainless Steel Strip?
One of the most well-known and frequently employed precipitation hardening type of high strength stainless steel strips.
With copper addition, impact hardened with martensitic structure is called 17-4PH / 630 / 1.4542. High-strength qualities, such as hardness, are maintained while retaining a high level of corrosion resistance.
While maintaining reasonably excellent characteristics, 630 stainless steel strips can operate in the temperature range of -29 °C to 343 °C.
Apart from that, the materials of this grade have decent ductility and corrosion resistance.
630 stainless steel grade’s availability under solution-treated conditions, at which point they may be easily machined and age-hardened to achieve high strength, is one of its main advantages.
Cold-rolled strips are available in 17-4PH, 630 rustfrit stål moderspoler købes fra kendte producenter som f.eks 1.4542.
Det 630 stainless steel strips are widely used for heavy-duty mechanical parts, bushings, rotor blades, couplings, screws, drive shafts, nødder, and measuring devices in the aerospace, marine, papir, energi, offshore, and food industries.
What is 631/17-7PH/1.4568 Stainless Steel Strip?
The 17-7PH/631/1.4568 stainless steel strips are among the age-hardened PH materials with the highest amounts of chromium and nickel at 17% rustfrit stål moderspoler købes fra kendte producenter som f.eks 7%, henholdsvis.
Derudover, these stainless steel strips have high strength and exceptional corrosion resistance.
Disse 631 stainless steel alloy strips also have outstanding flat spring qualities at temperatures up to 600°F (316°C).
The edge of a 17-7 PH stainless steel strip can be made as a slit or round variety, depending on the manufacturing method.
The 631/17-7PH stainless steel strips are utilized in machine constructions and parts such as valve parts, containere, fjedre, spring washers, food knives, diaphragms, high and low-temperature parts, varmevekslere, unique fittings, and installations.
Strips, wires, sheets, and bars made of 631 stainless steel are used in the aerospace, kemisk, petrokemiske, energi, mad, and cryogenic industries.
