SUS304 SUS904L Decorative Stainless Steel Handrail Accessories Pipe 1M ASTM
Applications of 440 Steel
Type 430 steel is a simple, inexpensive, and widely used stainless steel. While not a front runner in any one category, its combination of heat resistance, ductility, corrosion resistance, and low cost makes it a great general-purpose steel. Also, by modifying its composition slightly, 430F stainless steel can be easily machined, making a great machining alloy. Type 430 steel contests the top spot for the most widely used stainless steel, as it can be used in many applications such as:
Dishwasher linings,
Automotive trim,
Range hoods,
Drawn/formed parts,
Industrial roofing & wall cladding,
Utensils,
Handling equipment for mining,
Heat-resisting applications,
and more.
