Industry AISI 304 316L NO.1 finish hot rolled ss sheet stainless steel plate
Stainless steels are a family of iron based alloys that contain a minimum of 10.5% chromium (CR). The presence of chromium creates an invisible surface film that resists oxidation and makes the material passive or corrosion resistant (stainless). There are multiple families of stainless steel which are designed for various applications and uses. Stainless grades can be further modified to meet various processing, corrosion, temperature and strength conditions.
Stainless steel sheet/Plate can be made by cold rolling and hot rolling, including the thickness of 0.31-6.0 mm sheet and 3.0-60mm plate; common type 201, 202, 304, 304L, 316L, 309S, 310S, 317L, 347, 409L, 410S, 420J1/J2, 430, 446 etc.
Hot-rolled stainless steel, mechanical properties not as good as cold-rolled, but there are good toughness and ductility.
Cold-rolled stainless steel plate due to the good hardening, toughness is low.
In order to ensure all kinds of stainless steel yield strength, tensile strength, elongation and hardness and other mechanical properties to meet the requirements, prior to delivery must be stainless steel annealing, solution treatment, aging heat treatment.

Stainless steel 304 introduction:
304 alleviates this problem by decreasing the carbon content and thereby eliminating the possibility of intergranular corrosion. This low carbon alloy is most often utilized for applications requiring welding. An Extra Low Carbon alloy, Type 304L is also available for especially severe welding applications. Type 304L has the capability to avert any detrimental precipitation in the extreme 800° F. to 1650° F. range.
Applications
Both types are extremely popular in the food and dairy industries and for use in pharmaceutical equipment. It is exceedingly useful in applications where good mechanical properties and corrosion resistance are essential. It is highly desirable for products such as instrumentation where non-magnetism is fundamental. These grades are available in a wide range of forms and finishes.
Corrosion Resistance
Types 304 and 304L exhibit good corrosion resistant qualities, particularly those corrosions caused by atmospheric conditions or chemicals. They lose some resistance at temperatures of about 750° F. to 1500° F. due to carbide precipitation. Type 304L however, has excellent corrosion resistant capabilities within this temperature range because of its low carbon content. Maximum corrosion resistance in all these grades can be achieved by annealing.
Stainless steel 316 & 316L introduction
Type 316 is an electric furnace processed modification of Type 304: it contains 18% chromium; 10% nickel, and; 2-3% molybdenum. This addition of molybdenum increases both the corrosion resistance and the high temperature strength of this alloy. The most outstanding advantage of this addition is the increased corrosion resistance to reducing acids and pitting or pin hole corrosion. In general, Type 316 is known as the major all-around corrosion resistant austenitic stainless steel available. Under extremely elevated temperatures, Type 31 6 proves itself to possess remarkable creep and rupture strength, This non-heat treatable, non-magnetic alloy possesses excellent cold forming and drawing properties, making it suitable for a wide range of applications. Type 316L is an extra low carbon modification of Type 316 recommended for use during welding operations. The low carbon factor eliminates the possibility of harmful carbide precipitation in the 800° F. to 1500° F. range.
Applications
Type 316 and Type 316L find their greatest use in the chemical, textile, paper, pharmaceutical, and photographic industries because of their excellent resistance to chemical corrosion. They also find use where the combination of corrosion resistance and extremely high strength at elevated temperatures is necessary.
Corrosion Resistance
Type 316 is known to be more resistant to atmospheric and chemical corrosion than any other grade of the stainless steels. Maximum corrosion resistance may be obtained by fully annealing this alloy. If the application calls for welding, Type 316L should be used as it is highly resistant to carbide precipitation and intergranular corrosion. Which usually occurs at high temperatures.
