Grade 6.8 Carbon Steel Flat Washers Din 125A M30 Size High Corrosion Resistance

Carbon Steel Flat Washer Din125A Grade 6.8 M30 White Or Plain Color


Describe:


Carbon Steel Flat Washer Din125A Grade 6.8 M30 White Or Plain Color,the material is carbon steel,the size is M30,the thickness is 4mm,the surface treatment is white zinc plated,the standard is DIN125A.This is one of our main product.

According to the quality of carbon percentage is divided into:
1. Low-carbon steel (C: ≤0.25%), also known as mild steel, mild steel is easy to accept a variety of processing such as forging, welding and cutting, commonly used in the manufacture of chains, rivets, bolts, shafts and so on.

2. Medium carbon steel (C: 0.25% <C ≤ 0.6%) have a variety of products, such as killed steel, semi-killed steel, boiling steel. In addition to carbon can also contain a small amount of manganese (0.70% ~ 1.20%). According to the quality of products divided into ordinary carbon structural steel and high-quality carbon structural steel. Hot processing and cutting performance is good, poor welding performance. Strength, hardness than low carbon steel, plasticity and toughness than low carbon steel. Without heat treatment, direct use of hot-rolled material, cold drawn material, can also be used after heat treatment. Quenched and tempered carbon steel has a good comprehensive mechanical properties. The maximum hardness that can be achieved is about HB538 and the tensile strength σb is 600 to 1100 MPa. As a result, medium carbon steels are used most widely for a variety of applications at moderate levels of strength, except for construction materials, which are also used extensively in the manufacture of various mechanical parts.

3. High-carbon steel (C:> 0.6%), often referred to as tool steels, has a carbon content of greater than 0.60% to 1.70% and can be hardened and tempered. Hammers, crowbars, etc. made of steel with a carbon content of 0.75%; cutting tools such as drill bits, wire tapping, reamers and the like are made of steel having a carbon content of 0.90% to 1.00%.
