BMS bars (bright mild steel) are general-purpose carbon steel bars with an improved, cleaner surface finish. Advantages of using this steel include less wastage, a much cleaner surface, and increased straightness.
EN8 is an unalloyed medium carbon steel grade with reasonable tensile strength. It is normally supplied in the cold drawn or as rolled condition. EN8 is widely used for applications which require better properties than mild steel but does not justify the costs of an alloy steel.
En19 steel is a high quality engineering alloy steel containing chromium and molybdenum. It falls in a class of low alloy steel. It has high fatigue strength, abrasion and impact resistance, toughness, and torsional strength. It can be heat treated in a number of ways to give it a combination of properties.
EN19T (709M40T) is classed as a low alloy chromium molybdenum through-hardening steel. Unlike the majority of engineering steels, EN19T does offer fair corrosion resistance. Due to the materials' high tensile strength, EN19T is suitable for high-load applications such as gearboxes.
Grades 20MnV6, 2C and 4140 are used for all forms of mechanical engineering components, such as brushes, hydraulic cylinders, gear wheels, shafts, axles, stuffing boxes, lock nuts, spindles, drill jigs, rolls etc. Improved carbon steel grade, used to reduce machining time, good weldability.
