Stainless Steel 316L

	Material Notes Type 316L stainless steel in amolybdenumbearingaustenitic. It is more resistant to generalcorrosionand pitting than conventionalnickel chromiumstainless steels such as 302-304. It has the following characteristics: - Higher creep resistance - Excellent formability. - Rupture and tensile strength at high temperatures - Corrosion and pitting resistance
	Shapes vary based on the type ofindustrial application, e.g. wire, ribbon, strip, sheet and foil sizes to be used in cookware, cutlery,hardware, surgical instruments, major appliances, industrial equipment, and building material in skyscrapers and large buildings. For example, stainless steel cylinders and tanks are manufactured in 316 grade stainless steel, have proved to offer exceptional resistance inacidicandhardwater areas.
	Market Applications Chemical, pharmaceutical industry 外科手术和医疗工具,外科implants Paper industry digesters, evaporators & handling equipment Petroleum refining equipment Textile industry equipment, textile tubing Scrubbers for environmental control Duct works, feed-water tubes, sewagewater filters Heat exchanger tubes,ozone generators There are many industrial processes that require a higher level of resistance to corrosion than Type 304 can offer and therefore Type 316 is the answer.
	What does the L mean? L-grades have 0.03%carbonmaximum. L-grades are resistant to sensitization in short-term exposures or heat treatments. L-grade often have slightly lower (typically 5,000psiless) minimum strengths than standard stainless steels. Most standard grades of stainless steel have 0.08% maximum carbon and are suitable for use in non-welded parts and equipment; in case of welded applications these parts are used for light-gauge applications
