In some cases, one object may fall within more than one scale (see the hardness comparison chart). 15N Scale, 15 Kgf (15N) Rockwell Superficial Hardness No. 10mm Standard Ball, 3000 Kgf (HBS) Brinell Hardness No. Learn more about the mechanical properties of the 303 stainless steel materials we use in our threaded insert products. Rockwell Hardness Number C Scale, 150 Kgf (HRC) Vicker’s Hardness Number (HV) Brinell Hardness No. 316L stainless steel (UNS S31603) is the low carbon version of AISI 316. Soft steels are usually measured using the Rockwell B scale while harder steels and deep case-hardened steels are usually measured on the Rockwell C scale. In Duplex Stainless Steels, 1997. Due to the addition of Molybdenum (Mo), SS 316 has a great improvement in corrosion resistance and certain properties. Maximum Temperature: Corrosion. 30N Scale, 30 Kgf (30N) Rockwell Superficial Hardness No.45N Scale, 40 Kgf (45N) 48 Thermal Properties. Two terms accompany soft and hard Rockwell C-rated steel. Tensile Strength: Yield (Proof) 1230 MPa 180 x 10 3 psi. 5.3 Hardness. 76 GPa 11 x 10 6 psi. 400 °C 750 °F. 840 °C 1550 °F. High-rated RC hardness steels maintain their edge well, but it’s difficult to achieve sufficient sharpness. Tensile Strength: Ultimate (UTS) 1330 MPa 190 x 10 3 psi. 280 J/g. Rockwell Hardness Number C Scale, 150 Kgf (HRC): Rockwell Hardness Number A Scale, 60 Kgf (HRA): Rockwell Superficial Hardness No. The hardness of duplex parent materials has received attention, especially due to the NACE MR-01-75 requirements for sour service. Those are malleable and brittle. Rockwell C Hardness. Maximum Temperature: Mechanical. With industrial machine knives, extremely hard steel with an RC number in the 60s may be too fragile to use reliably. 800-219-9095 Fax: 800-219-9096 E-mail: firstname.lastname@example.org Web: www.labtesting.com 2331 Topaz Drive, Hatfield, PA 19440 Brinell Vickers Knoop Tensile Strength 10 mm Carbide Ball Diamond Pyramid Diamond Penetrator Steel C Scale 150 … Approximate Hardness Conversion No.’s for Austenitic Stainless Steel Sheet. Shear Modulus. 790 MPa 110 x 10 3 psi. The harder a steel becomes, the more brittle it is. AISI 316 stainless steel (UNS S31600) is one of the most widely used austenitic stainless steels.
