What is the difference between 321 and 321H?
The difference between 321 and 321H grades lies in the amount of carbon contained within each metal. 321 has at most 0.08% while 321H contains between 0.04% and 0.10% carbon. They both contain at most 2.0% manganese, 0.75% silicon and 0.045% phosphorous.
What is stainless steel Euro Inox?
Euro Inox is the European market development associa- tion for stainless steel. A prime objective of Euro Inox is to create awareness of the unique properties of stainless steels and to further their use in existing applications and in new markets.
What is the hardness of stainless steel?
Table 1: Summary of mechanical properties for 304 steel.

Is specification for stainless steel?
The most common grade of austenitic stainless steel is 304 (1.4301). A common name for 304 stainless is 18/8. This name refers to the average composition, 18% chromium and 8% nickel. It is sometimes used generically for austenitic stainless steel other than 304, even if the actual composition is vastly different.
What is the difference between 304 and 321 stainless steel?
321 stainless steel is known as stabilized grades of stainless steel, is Chromium nickel steel containing titanium. 321 stainless steel is basically from 304 stainless steel. They different by a very very small addition of Titanium. The real difference is their carbon content.
What is an INOX finish?
The descaled mill stainless steel (inox steel) finish has the welded seam smoothed over and has a very raw type of finish. It is an ideal solution where cost may be an issue yet you still require the corrosion resistance qualities for an external application. Commonly it may be painted or powder coated to finish.
What is 2B stainless steel?
2B: This is achieved by cold rolling, heat treating and pickling, along with the application of a light rolling at the end in order to achieve a smooth and reflective sheen. Considered the most widely used surface finish, 2B is the basis for most polished and brushed finishes.
Is stainless hard or soft?
Stainless steel is considered a soft metal meaning it is not great for many high load applications that require intense strength. However, certain grades are hardened to create a stronger version.
What are the physical properties of stainless steel?
Stainless Steel Characteristics
- Corrosion resistant.
- High tensile strength.
- Very durable.
- Temperature resistant.
- Easy formability and fabrication.
- Low-maintenance (long lasting)
- Attractive appearance.
- Environmentally friendly (recyclable)
What is strongest stainless steel?
Even among steel alloys, grade 304 stainless steel is noteworthy for its high tensile strength—roughly 621 MPa (90 ksi). Like most stainless steels, grade 304 has a high maximum operating temperature (about 870˚C).
