New Steel CRMs for April 2020 – Grades F9, 15-5PH, 1020 and 1050

Our Partner ARMI | MBH has been busy looking through data and certifying new material. We are proud to announce the release of 4 new Steel CRMs this month.  (click on the links in the names of each part to see the certificates of analysis.)

The new steel standards include an F9 (9%Cr, 1Mo), a 15-5PH steel, and two carbon steels – a 1020 and a 1050.

The new F9 steel; IARM-Fe9-18 falls in the typical range for the grade, with 8.72% Cr and 0.94% Mo, and has certified values for 19 other elements, As, C, Ca, Co, Cu, Fe, Mn, N, Nb, Ni, O, P, S, Sb, Si, Sn, Ti, V and W. This type of steel has many uses, and is good for mild corrosive or erosive applications, and can withstand a wide range of temperatures.

The 15-5PH steel; IARM-Fe155PH-18 contains 15.13% Cr; 4.79%  Ni and 3.35% Cu, and has certified values for an additional 17 elements, including Al, As, B, C, Co, Fe, Mn, Mo, N, Nb, O, P, S, Si, Sn, V and W.  15-5PH steels are martensitic precipitation hardening type steels, designed to be corrosion resistant and heat treatable for hardness.

There are two new Carbon steels; IARM-Fe1020-18, a 1020 low Carbon steel containing 0.226% C; and IARM-Fe1050-18, a 1050 medium Carbon steel containing 0.499%C. Carbon steels are among the most versatile steels, and the amount of Carbon in the steel correlates directly to its mechanical properties. Carbon steels are typically used for building, and railroads. Both of our new, commonly used, carbon steel grades are certified for several additional elements, including Al, As, Co, Cr, Cu, Fe, Mn, Mo, N, Nb, Ni, O, P, S, Sb, Si, Sn, V, and Zn. The 1020 low carbon steel is a new grade for us, and we are excited about being able to offer this in conjunction with all of our other steel products.
