18-8 grade stainless steel This refers to the 300 series of stainless steel with a chromium and nickel content in percentages. That means that an 18-8 grade fastener has 18 % chromium and 8 % nickel content. 18-8 type stainless steel has better resistance to corrosion than the 400 series. Mar 21, 2006 Type 304 heremon of austenitic grades, containing approximately 18 % chromium and 8 % nickel. It is used for chemical processing equipment, for food, dairy, and beverage industries, for heat exchangers, and for the milder chemicals. Type 316 Contains 16% to 18 % chromium and 11% to 14 % nickel. Question: What are the differences between 18 - 8 , type 304, and type 316 stainless steels? Answer: To answer this question, you first need to know some basic information about stainless steel. “ Stainless Steel ” is the general name for a large family of alloy steels that contain at least 10.5% chromium as part hereposition.
18 / 10 vs . 18 / 8 and 18 /0 stainless steel for flatware and pots pans Similarly, 18 /10 is usually referred to as 316 stainless steel, with 16-18 % Cr, . steel, versus lower grades of stainless steel on the market such as 304 and 18 / 8 . Dec 12, 2005 The 18 - 8 defines a family of alloys having 18 % chrome and 8 % nickel, the rest being iron and traces of lots of things, depending on the specific use. 316 is one alloy of the 18 - 8 family, having better corrosion resistance than some of the others. 18 8 Vs 316 Stainless Steel. 304 /304L STAINLESS STEEL DATA SHEET - AK Steel. 304/304L-S- 8 -01-07 AK Steel Type 304 is a variation of the basic 18 - 8 grade, Type 302, 304/304L STAINLESS STEEL DATA SHEET. 316 stainless steel - AK Steel Holding.
Type 316 is also used extensively for surgical implants within the hostile environment of the body. Type 316 is the main stainless used in the marine environment, with the exception of fasteners and other items where strength and wear resistance are needed, then Type 304 ( 18-8 ) is typically used. @Tick – 18-8 and 316 stainless will have the same mechanical properties (all things being equal). The advantage to 316 is that it is more corrosion resistant. The 304 stainless steel fasteners series is made up of approximately 18 % chromium and 8 % nickel ( 18 - 8 ). These fasteners, which also include the 302, 302HQ, 303 and 305, are characterized by multiple variables and grades with a hereposition.
