Stainless steel is a versatile material used in various industries, including automotive manufacturing. While 301 series stainless steel is not as common in automobile bodies as some other grades, it still finds applications in certain components. The 301 series belongs to the austenitic stainless steel group and is known for its high strength and corrosion resistance.
301 Series Stainless Steel
Grade | C | Si | Mn | P | S | Cr | Ni | Ti |
|---|---|---|---|---|---|---|---|---|
SUS301L-LT SUS301L-DLT | ≤0.12 | ≤0.08 | ≤2.00 | ≤0.035 | ≤0.03 | 17~19 | 8~11 | 0.5~0.8 |
SUS301L-ST SUS301L-MT | ≤0.07 | ≤1.00 | ≤2.00 | ≤0.045 | ≤0.015 | 17~18.5 | 8~10.5 | 0.7 |
SUS301L-HT | ≤0.03 | ≤1.00 | ≤2.00 | ≤0.045 | ≤0.015 | 17~18.5 | 8~8 | 0.7 |
The table lists several common austenitic stainless steels in current car production. LT material has excellent flatness and large elongation, and can be used as workpieces that do not require high strength; DLT material has a low cold rolling rate, so there is less residual stress and can be used as Workpieces processed by drawing and deep drawing;
ST material as a strong workpiece requires high strength and good elongation and can be used as a beam for forming processing such as drawing, bending, and deep drawing; MT material has higher strength
The material must be used as a high-strength workpiece forming material; HT material has the largest yield and tensile strength and is mainly used as a basic high-strength workpiece. Special attention must be paid to the plastic processing of this material.
301 Series Stainless Steel In Automobile Bodies
In the automotive industry, 300 series stainless steels, such as 304 and 316, are more commonly used for components like exhaust systems, trim, and some structural elements. These grades offer good corrosion resistance, durability, and formability.
Automobile bodies are typically made from sheet metal, and steel grades like mild steel, high-strength low-alloy (HSLA) steel, or advanced high-strength steel (AHSS) are commonly used due to their balance of strength, formability, and cost-effectiveness. However, stainless steel, including the 301 series, may be used in specific applications where corrosion resistance and strength are crucial.
