Stainless steel is an alloy that consists of iron and at least 10.5% chromium. Chromium makes the steel corrosion-resistant and gives it its distinct shine. The stainless steel grade 3cr13 is a type of stainless steel formulated for applications such as cutting tools, pipes and fittings. It contains 0.3% carbon, which makes it semi-porous, giving it greater strength than comparable grades of stainless steel with more carbon. In more detail, let’s explore the composition, mechanical properties, physical properties, and uses of 3cr13 stainless steel.
3CR13 Stainless Steel Composition
3cr13 SS is composed primarily of iron (Fe), with 13% chromium (Cr) and a maximum of 0.3% carbon (C). Additionally, it has trace amounts of manganese (Mn), phosphorus (P), sulfur (S), silicon (Si) and nitrogen (N).

3CR13 Stainless Steel Mechanical Properties
The mechanical properties of SS 3cr13 are quite impressive compared to other types of stainless steel. It has a tensile strength range from 70-85 ksi, a yield strength range from 40-50 ksi, an elastic modulus range from 28 to 29 million psi, and an elongation range from 10-15%. Furthermore, this type of stainless steel has good hardness ratings up to HRC52 on the Rockwell C scale.
3CR13 Stainless Steel Physical Properties
The physical properties of grade 3cr13 are also quite remarkable, with a density ranging from 7600-7700 kg/m³ and an electrical resistivity ranging from 1.39 x10³ Ω·m to 1.47 x10³ Ω·m at 20°C. Moreover, it has an excellent magnetic permeability rating of up to 100 relative permeability units at RT or room temperature, making it suitable for use in industrial applications such as magnetic sensors or motors where magnetic fields are present.
