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 έως 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 και 1.4542.
ο 630 stainless steel strips are widely used for heavy-duty mechanical parts, bushings, rotor blades, couplings, screws, drive shafts, ΞΗΡΟΙ ΚΑΡΠΟΙ, and measuring devices in the aerospace, θαλάσσια, χαρτί, ενέργεια, 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% και 7%, αντίστοιχα.
Επιπροσθέτως, these stainless steel strips have high strength and exceptional corrosion resistance.
Αυτά τα 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, δοχεία, ελατήρια, spring washers, food knives, diaphragms, high and low-temperature parts, εναλλάκτες θερμότητας, unique fittings, and installations.
Λωρίδες, wires, φύλλα, and bars made of 631 stainless steel are used in the aerospace, χημική ουσία, πετροχημική, ενέργεια, φαγητό, and cryogenic industries.
