What to consider when choosing stainless steel
Stainless Steel Tube is one of the greatest inventions in human history. It is a type of metal alloy made by combining steel with other metals such as nickel and chromium. What sets stainless steel apart from other materials is its versatility in myriad applications? Different grades can be adapted to different applications in different industries.
Here are seven things to consider when choosing the right stainless steel grade:
1. Welding requirements
Not all grades of stainless steel are weld able. Depending on the grade, welding may cause problems such as intergranular corrosion, high-temperature cracking, and stress corrosion cracking. If the product requires welding, select a weld able stainless steel grade. Austenitic stainless steels such as 304L and 347 CE have low carbon levels and can be used for welding. Ferrite stainless steels such as grade 430 and grade 439 can also be easily welded. Martens tic stainless steel is generally not suitable for welding.

2. Corrosion resistance
Stainless steel is known to be corrosion resistant, but different grades of stainless steel have different levels of corrosion resistance. Austenitic stainless steels such as grades 304 and 316 are required to be corrosion resistant by large amounts of chromium and molybdenum, respectively. Ferrite and martens tic stainless steels have less nickel and, in some cases, less chromium than austenitic stainless steels, which are generally more affordable than austenitic stainless steels and can reduce corrosion resistance. They limit exposure to elements and other corrosive elements, making them suitable for applications involving stainless steel indoors.
3. Need for machining
Most grades of stainless steel can be machined, but they are very susceptible to hardening. The machining process must be optimized to operate at speeds that help alleviate this problem, and the tools used for machining must also be kept in good working order. Similar to carbon steel, sulphur can be added to improve machinability. Grade 303 is an example of this. Very similar to Grade 304, except that sulphur is added for machining. Grade 416 is an example of sulphur-added ferrite stainless steel.
4. Heat treatment
When stainless steel is exposed to heat, it is essential to know how the properties of the product are affected. Grades 440C and 17-4 PH are heat-treated stainless steels.
The quality of stainless steel depends on several factors, and one of the most important factors to consider when choosing stainless steel is strength. The force varies to varying degrees. Martens tic stainless steels such as 440C grade and precipitation hardening stainless steels such as 17-4 PH and 15-5 PH have the highest strength. Austenitic stainless steel ranks second on the strength scale. Two-phase stainless steels can provide the properties of ferrite stainless steel while maintaining ductility and toughness close to those of austenitic stainless steel.
