304 stainless steel cannot be heat treated—instead it can be strengthened by cold working. It is weakest in the annealed condition, and is strongest in the full-hard condition. The tensile yield strength ranges from 210 to 1,050 MPa (30,000 to 153,000 psi).
17-4 stainless steel can be heat treated to approximately 44 Rc, [1] and an ultimate tensile strength of 1,300 MPa (190,000 psi). Its density ranges from 7,800 to 7,900 kg/m 3 (0.282 to 0.284 lb/cu in), and its modulus of elasticity ranges from 197 to 207 GPa (28.5 × 10 ^ 6 to 30.0 × 10 ^ 6 psi).
The ultimate tensile strength of a material is an intensive property; therefore its value does not depend on the size of the test specimen.However, depending on the material, it may be dependent on other factors, such as the preparation of the specimen, the presence or otherwise of surface defects, and the temperature of the test environment and material.
The most common type of stainless steel, 304, has a tensile yield strength around 210 MPa (30,000 psi) in the annealed condition. It can be strengthened by cold working to a strength of 1,050 MPa (153,000 psi) in the full-hard condition.
The "HY" steels are designed to possess a high yield strength (strength in resisting permanent plastic deformation). HY-80 is accompanied by HY-100 and HY-130 with each of the 80, 100 and 130 referring to their yield strength in ksi (80,000 psi, 100,000 psi and 130,000 psi). HY-80 and HY-100 are both weldable grades, whereas the HY-130 is ...
It has a yield strength up to 80,000 psi (550 MPa) but costs only 24% more than A36 steel (36,000 psi (250 MPa)). One of the disadvantages of this steel is that it is 30 to 40% less ductile . In the U.S., these steels are dictated by the ASTM standards A1008/A1008M and A1011/A1011M for sheet metal and A656/A656M for plates.
Zeron 100 is a super duplex stainless steel developed by Rolled Alloys (formerly Weir Materials). The alloy has excellent corrosion resistance combined with high strength. It typically contains 25% chromium and 7% nickel and 3.6% molybdenum along with copper and tungsten additions. Zeron 100 has a 50–50 austenitic–ferritic structure.
A36 steel has a Poisson's ratio of 0.26 and a shear modulus of 11,500 ksi (79.3 GPa). [ 7 ] A36 steel in plates, bars, and shapes with a thickness of less than 8 inches (203 millimeters) has a minimum yield strength of 36 ksi (250 MPa ) and ultimate tensile strength of 58–80 ksi (400–550 MPa).
