AISI steel specifications stockholders and suppliers, delivering to the whole of the UK. American Iron & Steel Institute AISI specifications cover a wide range of steel types, including carbon steel, alloy steel, tool steel and stainless steel. AISI steel grades are becoming increasingly popular in the UK, primarily due to their use in the oil and gas industries. AISI grades are sometimes referred to as SAE designations.
We hold a comprehensive range of stock in AISI material and AISI equivalent specifications. Of AISI steel grades available the majority are as carbon steels and alloy steels. AISI carbon steels and alloy steels are usually given a four digit number, the first two digits indicate the alloying element in the AISI specification and the last two digits indicate the amount of carbon in the specification. It is possible that AISI grades are quoted as SAE grades and it is often that AISI/SAE have the same steel identification number.
The AISI range of steel specifications also includes stainless steels which are 3 digit numbers starting with either a 2, 3, 4, or 5. The most popular of these being the 300 series austenitic stainless grades, followed by the 400 series martensitic grades.
Also stocked are AISI grades of tool steel and high speed steel. AISI tool steel and high speed steel specifications are usually designated with a letter followed by 1 or 2 digits.
