Know Your Stainless Steel Finishes - Ryerson
Considered the most widely used surface finish, 2B is the basis for most polished and brushed finishes. Such common stainless steel grades as 201, 304, 304L and 316L come in a standard 2B finish. • 2D This finish is also achieved by cold rolling, heat treating and pickling, but, unlike 2B, does not receive the light rolling.

4 Types of Metal That Are Corrosion Resistant or Don't Rust
Galvanized steel; Stainless Steel. Stainless steel types, such as 304 or 316, are a mix of elements, and most contain some amount of iron, which easily oxidizes to form rust. But many stainless steel alloys also contain a high percentage of chromium – at least 18 percent – which is even more reactive than iron.

Coal & steel | World Coal Association
Raw materials Steel production. Coke. Coking coal is converted to coke by driving off impurities to leave almost pure carbon. The coking coal is crushed and washed. It is then 'purified' or 'carbonised' in a series of coke ovens, known as batteries, where the coking coal is heated to 1000-1100ºC in the absence of oxygen for 12-36 hours.

Ferritic Stainless Steels - ASSDA
Ferritics account for approximately 25% of stainless steel use worldwide. The name arises because these alloys have similar properties to carbon steels when they are bent or cut and, unlike the well-known 304 and 316 austenitic grades, ferritics are strongly attracted to a magnet. There is a major misconception that ferritic stainless steels ...

steel mill - Everything2
A steel mill is a factory that makes steel.. So what is steel? And how is it made? Steel is an alloy of iron and a small amount of carbon, some of it forming a compound with iron called cementite.It is produced out of iron. "Normal" iron contains quite some carbon, so in order to make steel out of iron, you need to take out some of the carbon.
