Chemical composition % of the ladle analysis of grade AISI Steel and Standards

 

At Longhai steel we can supply you with AISI steel grades and also AISI equivalent grades to British & European standards. Please contact us with your specific requirements and we shall endeavour to help.

AISI steel grades (American Iron & steel Institute) are becoming increasingly popular in the UK, primarily due to their use in the oil and gas industry. 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. AISI materials grades are shown in the table below, as to how the four digit number indicates the type it refers to.

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 equivalent 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.

Principal Design Features

One of the most widely used precipitation hardening grades in the business. While soft and ductile in the solution annealed condition, it is capable of high properties with a single precipitation or aging treatment. Characterized by good corrosion resistance, high harness, toughness and strength.


Machinability

Long, gummy chips characterize this alloys machinability. It can be machined in the annealed condition, however condition H1150M will yield best results. Post machining solution treatment of parts will be required prior to final hardening if machining in this condition.


Heat Treatment

CONDITION A--Soak at 1900 F (1038 C) for 30 minutes and cool below 60 F (16 C) for complete martensite transformation. CONDITION H 950- Treat Condition A material at 900 F(482 C) for 1 hour, air cool.. CONDITION H925, H1025, H1075, H1100, H1150- Soak solution treated material for 4 hours at specified temperature, air cool, CONDITION H1150M- Soak solution treated material at 1400 F (760 C) for 2 hours, air cool, then re-heat to 1150 F (620 C) for 4 hours and air cool.


Welding

Successfully welded by common fusion and resistance methods, this alloy should not be joined by oxyacetylene welding. AWS E/ER630 filler metal is recommended if required.


Forging

Soak for 1 hour at 2150 F (1177 C) prior to forging. Do not work below 1850 F (1010 C). Post-work solution treatment is required prior to final hardening.
