Type 316L stainless steel density is 0.289 lb/in3 (8.0 g/cm3); melting point is 1375-1400 °C (2500-2550 °F); 0.2% yield strength is minimum 25 ksi (170 MPa) in annealed and hot finished condition, minimum 45 ksi (310 MPa) in annealed and cold finished condition; Minimum tensile strength is 70 ksi (485 MPa) in annealed and hot finished .Tensile strength can be calculated from hardness and is easy to determine because hardness tests — such as Rockwell — are simple to perform, inexpensive, and non-destructive because only a small penetration is performed on the specimen. For many metals, tensile strength increases as hardness increases. . Tensile strength test. Thermal .Converted from Brinell Hardness Value: Hardness, Rockwell B: 60: 60 Converted from Brinell Hardness Value: Hardness, Vickers: 107: 107 Converted from Brinell Hardness Value: Ultimate Tensile Strength: 310 MPa: 45000 psi AA; Typical: Tensile Yield Strength: 276 MPa: 40000 psi AA; Typical: Elongation at Break: 12 %: 12 % AA; Typical; 1/16 in.

Ultimate tensile strength of 6061 aluminium alloy depends greatly on the temper of the material, but for T6 temper it is about 290 MPa. . Rockwell hardness test is one of the most common indentation hardness tests, that has been .By way of correlation with other material properties, the Rockwell hardness test can provide important information about metallic materials, such as the tensile strength, wear resistance, and ductility. The test is generally useful for material selection, for process and quality control, and for acceptance testing of commercial products. .hardness tests - the Rockwell test is a measure of the resistance of material, specifically metals, to permanent indentation. Indentation hardness is not a fundamental . properties of materials, such as tensile strength and machinability. Furthermore, indentation hardness has become one of the most reliable controls of the heat treatment and .This results in 30 different Rockwell scales standardized according to ISO 6508 and ASTM E18 (e.g., A, B, C, 30N, 15T) or Rockwell test methods (e.g.: HRA, HRBW, HRC, HR30N, HR15TW), each covering different hardness ranges and consequently the widest variety of materials and applications (see table below).

The Brinell hardness number can be correlated with the ultimate tensile strength (UTS), although the relationship is dependent on the material, and therefore determined empirically. . Leeb rebound hardness test; Rockwell scale; Vickers .

An approximate relationship between the hardness and the tensile strength (of steel) is, . Rockwell A-Scale : 59~86 HRB >> Rockwell B-Scale : 41~100 . between hardness measures. Instead, one must correlate test results across the multiple hardness tests.

Ultimate Tensile Strength. Ultimate tensile strength of duplex stainless steels – SAF 2205 is 620 MPa. The ultimate tensile strength is the maximum on the engineering stress-strain curve. This corresponds to the maximum stress that can be sustained by a structure in tension. Ultimate tensile strength is often shortened to “tensile strength . for tensile strength in units of MPa (Ref 30).To generate a curve for Eq 6, diamond pyramid hardness values between 100 and 650 were converted to Brinell hardness according to ASTM E140-05 (Ref 29) and the tensile strength was calculated.Figure 4(a) shows Eq 6 overlaid on the tensile strength-hardness data. Figure 4(b) illustrates the difference in the predicted .

Rockwell hardness does have a relationship to tensile strength in some structural alloys, such as steel and aluminum. The Rockwell hardness test involves making an indentation on the test material. The indenter is either a conical diamond or a steel ball. Indenter ball diameters range from 1/16 to 1/2 inches and are chosen based on the test .Ultimate tensile strength is often shortened to “tensile strength” or even to “the ultimate.” If this stress is applied and maintained, fracture will result. . Rockwell hardness test is one of the most common indentation hardness tests, that has been developed for hardness testing. In contrast to Brinell test, the Rockwell tester .
