Commonly used Carbon Steel explained below: There is a wide range of steel grades for strip steels suitable for cold forming. The temperatures of tensile testing were in the range of 20-900 °C. The difference is somewhat uniform, but to make it distinguishable, all steel alloyed with higher than 8% of its weight of elements other than carbon and alloy is considered high-alloy steel. Carbon Steel has three main subgroups depending on how much carbon is in the metal: Low Carbon Steels/Mild Steels (up to 0.3% carbon), Medium Carbon Steels (0.3-0.6% carbon), and High Carbon Steels (more than 0.6% carbon). For these applications, Type 316 is the answer. Steel with carbon content between 0.29 - 0.54%, ductile and strong with low wearing properties. The most common grade of austenitic stainless steel is 304 (1.4301). It is made of alloy steel and has six radial lines on the top of the bolt head.
