The following is a discussion of the various types of stainless steel . 18-8: 300 series stainless steel having approximately (not exactly) 18% chromium and 8% nickel. The term "18-8" is used interchangeably to characterize fittings made of 302, 302HQ,...

Stainless steels are iron-based alloys containing a minimum of about 10.5% chromium; this forms a protective self-healing oxide film, which is the reason why this group of steels has their characteristic "stainlessness" or corrosion resistance. The ability...

Stainless steel is engineering material with good corrosion-resistance, strength and fabrication characteristics. They can readily meet a wide range of design criteria, including load, service life and low maintenance. Selecting the proper stainless steel...

Most decisions about which stainless steel to use are based on a combination of the following factors: What is the corrosive environment? – Atmospheric, water, concentration of particular chemicals, chloride content, presence of acid. What is the temperature...

There are many different types of surface finish on stainless steel . Some of these originate from the mill but many are applied later during processing, for example polished, brushed, blasted, etched and coloured finishes. The importance of surface finish...

Can I use stainless steel at low temperatures? Austenitic stainless steels are extensively used for service down to as low as liquid helium temperature (-269 deg C). This is largely due to the lack of a clearly defined transition from ductile to brittle...

What Is Stainless Steel ? Stainless steel is an alloy of Iron with a minimum of 10.5% Chromium. Chromium produces a thin layer of oxide on the surface of the steel known as the 'passive layer'. This prevents any further corrosion of the surface. Increasing...

Stainless steel is usually divided into 5 types: Precipitation hardening (PH) Stainless Steels - These stainless steel s can develop very high strength by adding elements such as Copper, Niobium and Aluminium to the stainless steel . With a suitable “aging”...

347 stainless steel is variant of the basic austenitic 18/8 Grade 304 with added Columbium – the introduction of Columbium stabilizes the steel and eliminates carbide precipitation which subsequently causes intergranular corrosion. The steel has excellent...

Stainless Steel Type 347 is a columbium/tantalum stabilized austenitic stainless steel. Like Type 321, it has superior intergranular-corrosion resistance compared to typical 18-8 type alloys. Since columbium and tantalum have stronger affinity for carbon...
