Steel AR500 vs SNC236

Steel · grade comparison

Steel AR500 and SNC236 are both steel grades. AR500 is the stronger of the two: yield strength 1,350 MPa (196 ksi) against 700 MPa (102 ksi) for SNC236, about 93% more; tensile strength follows at 1,650 MPa (239 ksi) vs 850 MPa (123 ksi). In exchange, SNC236 is the more ductile: elongation 20% versus 9% for AR500, and AR500 is harder (500 HB vs 250 HB). SNC236 runs hotter in service (400°C vs 250°C continuous). On the shop floor, SNC236 machines more easily (good vs not recommended) and SNC236 sits in a lower cost tier (budget, $) than AR500 (high, $$$$).

AR500Choose it when strength drives the design.

SNC236Choose it when the part is bent, formed or impact-loaded, or when the part sees heat.

AR500 vs SNC236 — frequently asked

Is AR500 stronger than SNC236?

Yes. AR500 has a typical yield strength of 1,350 MPa (196 ksi) against 700 MPa (102 ksi) for SNC236 — about 93% more. Tensile strength is 1,650 MPa (239 ksi) vs 850 MPa (123 ksi).

Which is cheaper, AR500 or SNC236?

SNC236 is the lower-cost material: it sits in the budget tier ($) while AR500 is high ($$$$). Part price depends far more on geometry, tolerance and quantity than on raw stock — upload a CAD file for a live quote.

Which is easier to machine, AR500 or SNC236?

SNC236. Its machinability rates good (55/100) against not recommended (12/100) for AR500; for welding the order is AR500 first (fair, 45/100) then SNC236 (fair, 40/100).
