‘Stainless’ is a term coined early in the development of these steels for cutlery applications. It was adopted as a generic name for these steels and now covers a wide range of steel types and grades for corrosion or oxidation resistant applications.
Stainless steels are iron alloys with a minimum of 10.5% chromium. Other alloying elements are added to enhance their structure and properties such as formability, strength and cryogenic toughness. These include metals such as:
Non-metal additions are also made, the main ones being:
The main requirement for stainless steels is that they should be corrosion resistant for a specified application or environment. The selection of a particular “type” and “grade” of stainless steel must initially meet the corrosion resistance requirements. Additional mechanical or physical properties may also need to be considered to achieve the overall service performance requirements.
301 is a low nickel, higher carbon variant of 304. Its dominant purpose is to increase the work hardening capability of this austenitic grade of stainless steel to produce very high strength thin strip and wire.
Approximate Composition – 16.5% Cr, 7% Ni, 0.07% C (Exact composition ranges vary between EN and ASTM standards).
This grade combines the following characteristics:
The high work hardening rate of 301 allows it to be used for a wide range of applications where “springiness” is the primary requirement. The degree of “springiness” varies with the amount of cold rolling for strip or cold drawing for wire products. In the EN spring steel standards, the cold worked conditions are designated in the form +C700 up to +C1900 where the number stands for the minimum UTS in MPa. The ASTM system uses designations such as ¼ hard, ½ hard, ¾ hard and full hard, which cover the range of minimum UTS from 860 to 1275 MPa for grade 301.
Applications which illustrate these features include:
Springs, banding, clamps, clips, airframe sections, roll formed sections, wire mesh, seat belts, push feed systems
Types 302, 304, 304L, and 305 stainless steels are variations of the 18 percent chromium – 8 percent nickel austenitic alloy, the most familiar and most frequently used alloy in the stainless steel family.
These alloys may be considered for a wide variety of applications where one or more of the following properties are important: resistance to corrosion, prevention of product contamination, resistance to oxidation, east of fabrication, excellent formability, beauty of appearance, ease of cleaning, high strength with low weight, good strength and toughness at cryogenic temperatures, ready availability of a wide range of product forms. Each alloy represents an excellent combination of corrosion resistance and fabricability. This combination of properties is the reason for the extensive use of these alloys which represent nearly one half of the total U.S. stainless steel production. Type 304 represents the largest volume followed by Type 304L. Types 302 and 305 are used in smaller quantities. These alloys are covered by a variety of construction or use of equipment manufactured from these alloys for specific conditions. Food and beverage, sanitary, cryogenic, and pressure-containing applications are examples.
Type 1.4401 / 316 is an austenitic chromium nickel stainless steel. It also contains molybdenum which increases its general corrosion resistance as well as the mechanical properties at elevated temperatures. The properties of type 1.4401 / 316 are similar to type 1.4301 / 304; however 1.4401 / 316 is stronger at elevated temperatures and also corrosion resistance is improved particularly against sulphates, phosphates and other salts as well as reducing acids such as sulphuric, sulphurous and phosphoric. Type 1.4404 / 316L is an extra low carbon version of type 1.4401 / 316. The 1.4404 / 316L grade is preferred over 1.4401 / 316 for the weld condition since low carbon levels enhance resistance to intergranular corrosion.
