The tensile data for 17-4PH hardened stainless steel is 200,000 (psi) min. This indicate that the alloy does not possess the high tensile elongation characteristic of the austenitic stainless steels. 17-4PH hardened stainless steel material is capable of being mildly formed but is not capable of being severely formed. Forming is more easily accomplished in the overaged (such as H 1150-M from SA 693) condition than in the annealed, condition.
1.4542, 17-4PH martensitic stainless steel is a chromium-nickel grade of stainless that may be hardened by a single low temperature precipitation-hardening heat treatment. 1.4542/17-4PH hardened stainless steel plates and sheets are characterized by excellent mechanical properties at a high strength level may be obtained by such treatment. The corrosion resistance of 17-4PH is superior to that of hardenable straight chromium grades such as 416. Scaling and distortion is minimized. 17-4PH should not be used in the solution treated condition. The strength and corrosion resistance properties of 17-4PH martensitic stainless steel hold up well is service temperatures up to 800° F. Fabrication techniques for this steel is similar to those established for the regular stainless grades. 17-4PH martensitic stainless steel machines well, has excellent welding characteristics, and forges easily. The combination of good mechanical and processing properties makes this grade adaptable to a wide range of uses.
Applications: 17-4PH hardened stainless steel sheets/ plates are used where high strength and good corrosion resistance are required, as well as for applications requiring high fatigue strength, good resistance to galling, seizing and stress corrosion. Suitable for intricate parts requiring extensive machining and welding, and/or where distortion in conventional heat treatment is a problem.
GB T 5312 Carbon and carbon-manganese steel seamless steel tubes and pipes are mainly for ship use, also known as shipbuilding steel pipes. Under GB T 5312, there are mainly 5 steel grades: grade 320, 360, 410, 460 and 490. Each grade covers three levels: I, II, III.
Angle steel, commonly known as angle iron, is a long strip of steel whose sides are perpendicular to each other. There are equal angle steels and unequal angle steels. The two sides of equal angle steel are equal in width. The unequal angle steel is also known as L shape profile steel.
Flat bar steel can be produced according to the user's needs, with fixed thickness, width and length. It can reduce the cutting process for users, reduce the consumption of labor and materials, and also reduce the processing loss of raw materials.
