Laser cutting coating processing stainless steel stamping parts
Stainless steel stamping parts application
Stainless steel deep drawn parts are commonly used in the automotive industry for fuel delivery parts, brake parts, oxygen sensors, exhaust parts, decorative parts, such as lug nut covers, and so on.
Stainless steel stamping parts have the following ideal characteristics:
| Stainless steel is very strong and has a high strength-to-weight ratio |
| Stainless steel corrosion resistance |
| Stainless steel is generally considered non-magnetic, but some grades are magnetic (provides electrical benefits) |
| Stainless steel can be heat treated |
| Stainless steel has very good wear resistance |
| No need for plating stainless steel |
| Stainless steel can be polished in many ways to achieve decorative purposes |
Commonly Cast Stainless Steel Alloys:
Stainless Steel 304(1.4308)
This is the most common stainless steel and is applied in different applications. It consists of at least 18% chromium and 8% nickel and has no magnetic properties within its austenitic structure.
Stainless Steel 304L(1.4309)
Corresponds to stainless steel 304. The ‘L’ stands for ‘low carbon’, so this stainless steel has a lower carbon amount to increase weldability and to limit the corrosion sensitivity after welding.
Stainless Steel 316(1.4408)
A better, but more expensive type of corrosion resistant steel is stainless steel 316. This alloy contains at least 16% chromium, 10% nickel and 2% molybdenum. Because of the addition of molybdenum, this stainless steel type is better defended against salt corrosion and acids, and is often applied in chemical industries.
Stainless Steel 316L(1.4409)
Comparable to stainless steel 316 but with a lower carbon level to increase weldability of the stainless steel.
17-4 PH(1.4549)
A high quality stainless steel which is regularly used in the aircraft industry. It is characterized by a high tensile strength, hardness, toughness and is also corrosion resistant.
