SPECS
Chemical Composition (typical ranges)
Carbon Silicon Manganese Sulphur Phos. Typical % 2.6-3.75 1.8-3.0 0.6-.95 0.07Max 0.12 Max
Mechanical Properties
Mechanical Properties
Brinell Hardness
Compressive Strength
Heat Treat Response
27,000 - 40,000 psi depending on section size *As taken from bar mid-radius. Tensile strength decreases as section size increases and is dependant on test bar type/location.
As-Cast, Milled & Saw Cut
183 - 285 depending on section size
Typically 3-4 times tensile strength
Can be hardened by conventional heat treat methods to Rc 50 minimum. Hardness will decline to below Rc 50 beginning at appox. .200" deep.
