Stainless steel is 100% recyclable . An average stainless steel object is composed of about 60% recycled material of which approximately 40% originates from end-of-life products and about 60% comes from manufacturing processes. According to the International Resource Panel's Metal Stocks in Society report. , the per capita stock of stainless steel in use in society is 80–180 kg in more developed c...

Brushed or dull polished metal is metal with a unidirectional satinfinish. It is produced by polishing the metal with a 120–180 grit belt or wheel then softening with an 80–120 grit greaseless compound or a medium non-woven abrasive belt or pad.Commonly brushed metals include stainless steel , aluminium and nickel. Brushed finishes are popular in both small appliances and whiteware, and feature i...

Mill finish refers to the surface textures (or finish) of metal after it exits a rolling mill , extrusiondie, or drawing processes, including sheet, bar, plate, or structural shapes. This texture is usually rough and lacks lustre; it may have spots of oxidation or contamination with mill oil. Most mill finish surfaces are machined or treated with polishing, industrial etching, or some other surf...

Stainless steel differs from carbon steel by the amount of chromium present. Unprotected carbon steel rusts readily when exposed to air and moisture. This iron oxide film (the rust) is active and accelerates corrosion by making it easier for more iron oxide to form. Since iron oxide has lower density than steel, the film expands and tends to flake and fall away. In comparison, stainless s...

In metallurgy, stainless steel, also known as inox steel or inox from French inoxydable (inoxidizable), is a steel alloy with a minimum of 10.5% chromium content by mass.Stainless steel is notable for its corrosion resistance, and it is widely used for food handling and cutlery among many other applications.Stainless steel is used for corrosion-resistant tools such as this nutcracker.Stainless s...

The application of stainless steel tubes are divided into civil use and industrial use. The industrial stainless steel is widely use, including petroleum, chemical, natural gas and electrical equipment manufacturing industry. Its main features are strong acid and alkali corrosion resistance, heat resistance, low temperature intensities and mechanical properties, stamping, bending which are good at...

According to the production processes, stainless steel tubes divided into seamless tubes and welded tubes. The raw material of seamless steel tube is the round bar billets. Its production techniques are hot rolling and cold drawing.Production processes of hot rolling seamless stainless steel tube : round bar billets →heating→punch the hole→three roll cold cross rolling, rolling in succession and e...

FineryDuring the refining process, the oxygen andintert gases (argon and nitrogen) will be blown into the liquid steel to makean effect of false vacuum. Therefore, it can decrease the content of carbon andresist the chromium from oxidized. As for the stainless steel material whichproduced by this way, the quality will be relatively high and good in extension.Intermediate frequency furnace 1.The ca...

Hot rolling is above the recrystallization temperature of rolling; Cold rolling is below the recrystallization temperature of rolling, both are based on the hot strip rolling.And then recover its mechanical properties by annealing . It generally underprocess such as hot rolling,acid pickling, cold rolling and annealing. There is no oxide coating during cold rolling process. Inthis way, the surface...

AISI 304（American Standard) is also named EN 1.4301( Europe Norm), which has capacity of high corrosion resistance, mechanic property and surface processing. It mainly contains Cr 18%, Ni 8%~10%, C≤0.08%，Mn 2%, Si 1%, P 0.045%, S 0.03%. Chemical element of stainless steel efficiently impacts the performance of corrosion resistance and working time. Lower Cr% and Ni% or higher C% directly affect t...

304 stainless steel is used for a variety of household and industrial applications such as screws, machinery parts, car headers, and food-handling equipment. # 304 stainless steel is also used in the architectural field for exterior accents such as water and fire features.

304 stainless steel, also known as stainless steel (18/8 stainless steel,) European norm 1.4301, is the most common stainless steel. The steel contains both chromium (usually 18%) and nickel (usually 8%) metals as the main noniron constituents.It is an austenite steel. It is not very electrically or thermally conductive and isnon-magnetic. It has a higher corrosion resisitance than regualr...
