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 °С.
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 а также 1.4542.
В 630 stainless steel strips are widely used for heavy-duty mechanical parts, bushings, rotor blades, couplings, screws, drive shafts, орехи, and measuring devices in the aerospace, морской, бумага, энергия, 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% а также 7%, соответственно.
Кроме того, these stainless steel strips have high strength and exceptional corrosion resistance.
Эти 631 stainless steel alloy strips also have outstanding flat spring qualities at temperatures up to 600°F (316°С).
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, контейнеры, пружины, spring washers, food knives, diaphragms, high and low-temperature parts, теплообменники, unique fittings, and installations.
Полоски, wires, sheets, and bars made of 631 stainless steel are used in the aerospace, химический, нефтехимический, энергия, еда, and cryogenic industries.

What are the Grade 630 Stainless Steel Strips and Grade 631 Применение полос из нержавеющей стали?
В 630 stainless steel strips are used in components for valves, болты, and gears, Dies for molding plastic, Boat propeller shafts and high-strength pump shafts, and Elements of an engine.
В целом, in situations where high strength or hardness is required, with some degree of corrosion resistance, the majority of uses are for precipitation-hardening 630 полосы из нержавеющей стали. These strips are used in the aerospace and other high-tech industries because of their high strength. Some other important applications consist of the following:
Transfer of power High-quality engine components such as gears, клапаны, stronger shafts, steam turbine blades, and molding dies are also available.
В 631 stainless steel strip has excellent welding performance, прочность, and hardness. Washers and springs are the main applications for stainless steel strips of grade 631/17-7. It is employed in those applications when great strength and corrosion resistance are required. Due to its minimal thermal distortion, it is also used in complicated parts.
The aerospace, нефтехимический, химический, and petrochemical sectors, as well as the energy, еда, and cryogenic industries, all use stainless steel 631strips. Due to its low distortion during heat treatment, it is also used in complicated parts.
Which one between Grade 630 Stainless Steel Strip and Grade 631 Stainless Steel Strip is better?
Обе 630 а также 631 stainless steel strips are widely used in many applications and are very popular among customers.
Сорт 631 полоса из нержавеющей стали лучше, чем 630 stainless steel due to extra Nickel contents and the addition of aluminum content in its composition.
The additional nickel content can increase the corrosion resistance and strength of 631 полосы из нержавеющей стали.
The tensile and yield strength of 631 stainless steel strips is more than 630 полосы из нержавеющей стали.
Заключение
These two stainless steel strips have their importance in the industry.
В 630 а также 631 stainless steel strips have excellent corrosion resistance, твердость, прочность, and stability at high temperatures.
Due to excellent properties, these grades of stainless steel strips are in demand these days.
