1.What is angle steel?

Steel angle, also named angle iron, or steel angle bar, is basically manufactured by hot-rolled carbon steel or high strength low alloy steel. It has L-cross shaped section with two legs - equal or unequal and the angle would be 90 degree.

 

2.What are the 4 types of steel?

The Four Types of Steel

Steel is a combination of two elements, iron and carbon. Steel are broken is broken into four types and then in those types steel is broken down into grades. There are four main types of steel, Carbon Steels, Alloy Steels, Stainless Steels, Tool Steels
