The term
stainless steel refers to an iron-based alloy – for instance, an alloy
containing a minimum of chromium, like up to 10.5% chromium, considered as
stainless steel. This amount on other materials, namely molybdenum, carbon,
manganese, and nickel, results in different types of stainless steel to
work-out on several applications. There might be grades on which types are
based to work differently, but stainless steel is generally divided into four
distinct groups; authentic, ferritic, duplex, martensitic.
Top 4 Groups of Stainless Steel:
1. Austenitic:
The
austenitic group comprises the most common types of stainless steel compared to
other types. Also, it contains elevated levels of chromium, nickel, and
molybdenum. It is known as a group that particularly versatile and renowned for
displaying excellent strength and malleability.
2. Ferritic:
This group
might contain chromium between 10.5 to 30% but usually have low carbon
consistencies of not more than 0.1%. Moreover, ferritic stainless steel is
magnetic and mainly preferred for its resistance to temperature oxidation and
strain corrosion cracking.
3. Duplex:
This group
combines both the groups' features, austenitic and ferritic, which fallouts in
a sturdier metal that is more durable than them both. The advanced strength of
duplex stainless-steel leads to significant weight reductions. This group's
exceptional resistance to corrosion, even in demanding environments, makes it
an ideal one for use in marine applications.
4. Martensitic:
This group
is structurally similar to ferritic stainless steel, but it has an elevated
carbon content of up to 1.2%. It is said that the martensitic group is prone to
be hardened to a greater degree. Martensitic stainless steel is used
specifically for creating medical tools and other surgical instruments.
The Most Common Industries Where Stainless Steel Is Used:
Stainless steel custom parts
are resistant to corrosion and low maintenance, making them ideal to use and
effective solutions for everyday applications. It's made in various forms,
including plates, sheets, bars, coils, and tubing for industrial and domestic
settings. A wide spectrum of industries depends on stainless steel – for
instance, architecture and construction, medical line, food, and catering, the automotive industry, energy, and other heavy industries.
