4340 steel is an ultra-high strength steel classified a medium-carbon, low-alloy steel. 4340 ... have yield strengths of 740-1860 MPa, tensile strengths of 860-1980 ...
The tensile yield strength of A514 alloys is specified as at least 100 ksi (689 MPa) for thicknesses up to 2.5 inches (63.5 mm) thick plate, and at least 110 ksi (758 MPa) ultimate tensile strength, with a specified ultimate range of 110–130 ksi (758–896 MPa). Plates from 2.5 to 6.0 inches (63.5 to 152.4 mm) thick have specified strength of ...
ASTM A325 is an ASTM International standard for heavy hex structural bolts, titled Standard Specification for Structural Bolts, Steel, Heat Treated, 120/105 ksi Minimum Tensile Strength. It defines mechanical properties for bolts that range from 1 ⁄ 2 to 1 + 1 ⁄ 2 inches (13 to 38 mm) in diameter.
High Tensile Strength Flat products: Minimum Yield Case: If followed by T then the given mechanical property is minimum tensile strength D: Flat Products for Cold Forming: Followed by C, D or X and two numbers characterising steel T: Tinmill Products: Nominal Yield Case: M: Electrical Steel: Number = 100 × specific loss in W/kg Number = 100 × ...
Tensile strength (min) [MPa] Core hardness [Rockwell] Class 4.6 Low or medium carbon steel: 5–100: 225: 240: 400: B67–95 Class 4.8 Low or medium carbon steel; fully or partially annealed: 1.6–16: 310: 340: 420: B71–95 Class 5.8 Low or medium carbon steel; cold worked: 5–24: 380: 420: 520: B82–95 Class 8.8 [6] Medium carbon steel ...
Type 304L—same as the 304 grade but lower carbon content to increase weldability. Is slightly weaker than 304. Type 304LN—same as 304L, but also nitrogen is added to obtain a much higher yield and tensile strength than 304L. Type 305—same as 304, but with more nickel to decrease work hardening.
A hypoeutectoid carbon steel (carbon composition smaller than the eutectoid one) is heated to approximately 30 to 50 °C (86 to 120 °F) above the austenictic temperature (A 3), whereas a hypereutectoid steel is heated to a temperature above the eutectoid one (A 1) for a certain number of hours; this ensures all the ferrite transforms into ...
ASTM A500 is a standard specification published by the ASTM for cold-formed welded and seamless carbon steel structural tubing in round, square, and rectangular shapes. It is commonly specified in the US for hollow structural sections, but the more stringent CSA G40.21 is preferred in Canada.
