What is the difference between 316 stainless steel and 304 stainless steel?
316 Stainless steel:
316 stainless steel, 18Cr-12Ni-2.5Mo Because of the addition of Mo, it has excellent corrosion resistance, atmospheric corrosion resistance and high temperature strength, and can be used under harsh conditions; excellent work hardening (non-magnetic). Equipment for the use of equipment, chemicals, dyes, paper, oxalic acid, fertilizers, etc. in seawater; photo, food industry, coastal facilities, ropes, CD rods, bolts, nuts. 316 stainless steel chemical composition: C ≤ 0.08, Si ≤ 1.00, Mn ≤ 2.00, P ≤ 0.035, S ≤ 0.03, Ni: 10.0-14.0, Cr: 16.0-18.5, Mo: 2.0-3.0. 316 stainless steel mechanical properties, tensile Strength (Mpa) 620 MIN, yield strength (Mpa) 310 MIN, elongation (%) 30 MIN, area reduction (%) 40 MIN, 316 stainless steel density 8.03 g/cm3, austenitic stainless steel generally uses this value .
304 stainless steel:
304 stainless steel is a common material in stainless steel with a density of 7.93 g/cm3, also known as 18/8 stainless steel. With high temperature resistance of 800 °C, it has the characteristics of good processing performance and high toughness.

Among the common marking methods on the market are 06Cr19Ni10 and SUS304, of which 06Cr19Ni10 generally represents the national standard production, 304 generally represents the ASTM standard production, and SUS 304 represents the Japanese standard production.

304 is a versatile stainless steel that is widely used to make equipment and parts that require good overall performance (corrosion resistance and formability). In order to maintain the corrosion resistance inherent in stainless steel, the steel must contain more than 18% chromium and more than 8% nickel. 304 stainless steel is a grade of stainless steel produced in accordance with American ASTM standards.
The main differences between 304 stainless steel and 316 stainless steel are:
1. The difference between the main components of metal
Both 304 stainless steel and 316 stainless steel contain about 16-18% chromium, but 304 stainless steel contains an average of 9% nickel, while 316 stainless steel contains an average of 12% nickel. Nickel can improve high temperature durability, improve mechanical properties, and improve oxidation resistance in metallic materials. Therefore, the nickel content of the material directly affects the overall performance of the material.

2, the difference in material properties
304 (0Cr18Ni9) stainless steel is austenitic stainless steel, can not be strengthened by heat treatment, can not be quenched like carbon steel, no magnetic. 304 has excellent mechanical properties, and has considerable corrosion resistance and high temperature resistance. It is the most widely used as stainless steel.
316 (0Cr17Ni12Mo2) stainless steel is the second most widely used steel grade after 304. Its main characteristics are acid and alkali resistance and high temperature resistance. It is mainly used in food industry and surgical equipment, and 316 stainless steel. Another notable feature is that there is basically no thermal expansion and contraction, which is extremely important for precision parts.

What is the Tempered glass?
Tempered glass/Reinforced glass is a safety glass. Tempered glass is actually a kind of prestressed glass. In order to increase the strength of the glass, chemical or physical methods are usually used to form compressive stress on the surface of the glass. When the glass is subjected to external force, the surface stress is first offset, thereby improving the bearing capacity and enhancing the resistance of the glass itself. Wind pressure, cold and heat, impact and so on. Note that it is distinguished from FRP.
Tempered glass is obtained by first cutting the ordinary annealed glass into the required size and then heating it to about 700 degrees near the softening point, and then performing rapid and uniform cooling (usually 5-6MM glass is heated at 700 °C for 240 seconds). Cool down for about 150 seconds. 8-10MM glass is heated at 700 °C for about 500 seconds, and the temperature is lowered by about 300 seconds. In short, depending on the thickness of the glass, the time for heating and cooling is different. After the tempering treatment, the surface of the glass forms a uniform compressive stress, while the inside forms a tensile stress, which improves the bending and impact strength of the glass, and its strength is about four times that of the ordinary annealed glass. The tempered glass that has been tempered can not be processed or damaged by any cutting, grinding, etc., otherwise it will be broken due to the damage of uniform compressive stress.
Features:
safety
When the glass is damaged by external force, the debris will become a honeycomb-like obtuse-angled small particle, which is not easy to cause serious damage to the human body.
high strength
The impact strength of tempered glass of the same thickness is 3 to 5 times that of ordinary glass, and the bending strength is 3 to 5 times that of ordinary glass.
Thermal stability
Tempered glass has good thermal stability, and can withstand a temperature difference of three times that of ordinary glass, and can withstand a temperature difference of 300 °C.
