Steel CP1000 vs MS1300

Steel · grade comparison

Steel CP1000 and MS1300 are both steel grades. MS1300 is the stronger of the two: yield strength 1,150 MPa (167 ksi) against 800 MPa (116 ksi) for CP1000, about 44% more; tensile strength follows at 1,380 MPa (200 ksi) vs 1,050 MPa (152 ksi). In exchange, CP1000 is the more ductile: elongation 8% versus 5% for MS1300, and MS1300 is harder (405 HB vs 315 HB). On the shop floor, CP1000 welds better (65 vs 55 out of 100) and MS1300 sits in a lower cost tier (budget, $) than CP1000 (standard, $$).

CP1000Choose it when the part is bent, formed or impact-loaded, or when it will be welded.

MS1300Choose it when strength drives the design, or when cost is the deciding factor.

CP1000 vs MS1300 — frequently asked

Is MS1300 stronger than CP1000?

Yes. MS1300 has a typical yield strength of 1,150 MPa (167 ksi) against 800 MPa (116 ksi) for CP1000 — about 44% more. Tensile strength is 1,380 MPa (200 ksi) vs 1,050 MPa (152 ksi).

Which is cheaper, CP1000 or MS1300?

MS1300 is the lower-cost material: it sits in the budget tier ($) while CP1000 is standard ($$). 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, CP1000 or MS1300?

CP1000, by a small margin. Both rate poor for machinability — 28/100 against 20/100 for MS1300; for welding the order is CP1000 first (good, 65/100) then MS1300 (good, 55/100).
