    The three main types of Stainless Steel Threaded Rod: austenitic, ferritic, and martensitic. These three types of steels are articular by their microstructure or absolute clear phase.

    Austenitic:

    Austenitic steels accept austenite as their primary appearance (face centered cubic crystal). These are alloys absolute chromium and nickel (sometimes manganese and nitrogen), structured about the Type 302 agreement of iron, 18% chromium, and 8% nickel. Austenitic steels are not hardenable by calefaction treatment. The a lot of accustomed stainless animate is apparently Type 304, sometimes alleged T304 or artlessly 304. Type 304 surgical stainless animate is an austenitic animate absolute 18-20% chromium and 8-10% nickel.

    Ferritic:

    Ferritic steels accept ferrite (body centered cubic crystal) as their capital phase. These steels accommodate adamant and chromium, based on the Type 430 agreement of 17% chromium. Ferritic animate is beneath adaptable than austenitic animate and is not hardenable by calefaction treatment.

    Martensitic:

    Martensite gives animate abundant hardness, but it aswell reduces its courage and makes it brittle, so few steels are absolutely hardened. There are aswell other grades of stainless steels, such as precipitation-hardened, duplex, and casting stainless steels. Stainless animate can be produced in a array of finishes and textures and can be brave over a ample spectrum of colors.

    Example:

    Type 304 Stainless (18-8)

    Chromium 18.00/20.00%, Nickel 8.00/10.50%

    Type 304 stainless has consistently been the a lot of economical stainless accessible and has been the industry accepted for the akin of bane attrition and backbone required.

    Type 316 Stainless

    Chromium 16.00/18.00%, Nickel 10.00/14.00, Molybdenum 2.00/3.00

    Type 316 Stainless is molybdenum address austenitic animate with increases percentages of nickel and able of abacus 2.5 to 5 times the bane attrition over apparent 304 Stainless. It is more attrition to pitting bane than archetypal 18-8 alloys.
