How much do you know about the steel of metal stamping?

Steel is the most widely used material for building the world’s infrastructure and industries, which is used to fabricate everything from sewing needles to oil tankers, such as in cars and construction products, refrigerators and washing machines, cargo ships and surgical scalpels. And Steel is one of the world's most-recycled materials, with a recycling rate of over 60% globally without loss of property. Steel is an alloy of iron and carbon containing less than 2% carbon and 1% manganese and small amounts of silicon, phosphorus, sulphur and oxygen.
