As with most steels, A36 has a density of 0.28 pounds mass per cubic inch (7.8 grams per cubic centimeter). Young's modulus for A36 steel is 29,000 kilopounds per square inch (200 gigapascals). [6] A36 steel has a Poisson's ratio of 0.26 and a shear modulus of 11,500 ksi (79.3 GPa). [7]
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.
It is also known as the strength-to-weight ratio or strength/weight ratio or strength-to-mass ratio. In fiber or textile applications, tenacity is the usual measure of specific strength. The SI unit for specific strength is Pa ⋅ m 3 / kg , or N ⋅m/kg, which is dimensionally equivalent to m 2 /s 2 , though the latter form is rarely used.
American steel grades : AISI/SAE steel grades standard; British Standards; International Organization for Standardization ISO/TS 4949:2016; European standards – EN 10027; Japanese steel grades : Japanese Industrial Standards (JIS) standard and NK standard; Germany steel grades : DIN standard; China steel grades : GB standard; Czech steel ...
As can be estimated from weight loss and the density , the wear coefficient can also be expressed as: [2] K = 3 H W P L ρ {\displaystyle K={\frac {3HW}{PL\rho }}} As the standard method uses the total volume loss and the total sliding distance, there is a need to define the net steady-state wear coefficient:

Higher-strength ABS shipbuilding steel comes in six grades of two strengths, AH32, DH32, EH32, AH36, DH36, and EH36. [ 3 ] The 32 grades have yield strength of 45,500 psi (315 MPa), and ultimate tensile strength of 64,000 - 85,000 psi (440-590 MPa).
