Stainless steels are high-alloy steels that provide superior corrosion resistance compared to carbon steels and low-alloy steels. There are five different types of stainless steel: Austenitic, Ferritic, Martensitic, Precipitation Hardened (PH), and Duplex. Many stainless steel alloys contain at least 10% chromium, which is largely responsible for their high corrosion resistance. For each category, there is one basic alloy that can be used for a variety of purposes. Depending on the application, smaller changes in the composition of the base are made to create specific properties.
Stainless steel is a versatile material because of its strength, corrosion resistance and ease of maintenance. Furthermore, it is a long-life product, and it is completely recyclable as well. Among its applications are: architecture and construction, automotive and transportation, medicine, energy and heavy industries, food and catering, and aerospace.
There are five types of stainless steel: austenitic, ferritic, martensitic, duplex (austenitic-ferritic), or precipitation. There are different grades of stainless steel in each category, every one of them different in terms of quality, durability, and heat resistance
Ferritic Stainless Steel
In comparison with austenitic steel, ferritic stainless steel is magnetic, low-corrosion, and heat-resistant. 430,446 These two grades are commonly used in the manufacture of automotive parts and kitchen appliances.
Martensitic Stainless Steel
Martensitic Stainless Steel, magnetic, moderate corrosion resistance, with a high temperature range, type 416, 420, 440, widely used in knives, firearms, surgical instruments, hand tools.
Austenitic Stainless Steel
The austenitic stainless steel is non-magnetic, highly corrosion resistant, and highly heat resistant. The 304,316 stainless steel and 316L alloys are used for food processing equipment, bolts, nuts, and other fasteners
Precipitation Hardened Or PH
Strongest grade of corrosion resistant stainless steel, precipitation hardened. Mostly used in aerospace applications, 17-4 PH and 15-5 PH
Duplex Stainless steel
Water treatment plants, and pressure vessels use duplex steels that mix both austenitic and ferritic elements. 244,2304,2507 are some of the most commonly used grades.
Stainless Steel Machining
Our company provides machining services for stainless steel of all types. Stainless steel 303 has high machinability, while stainless steel 316 has the lowest machinability among stainless steels. Stainless steels 17-4PH and 15-5PH tend to be easier to machine than stainless steels 316L.
Having high machineability means it takes less time to machine the parts. It is possible to achieve superior surface finishes by using smaller machines with less power. Cutting tools will not get dull as quickly, and the machines can handle the increased cutting feeds and speeds. Get a Machining Quote
