Product Description:

316L is a stainless steel grades, said the main containing Cr, Ni, Mo digital percentage probably contains (not accurate, probably only), 316L is the material corresponding US label, Sus 316L is corresponding to the Japanese label. Standard of our country as 022Cr17Ni12Mo2. (new standard) of old brand 00Cr17Ni14Mo2

316L - C: chemical composition of carbon less than 0.030 silicon Si: less than or equal to 1

Manganese: less than 2 Mn

316L S: less than 0.030 sulfur

P: less than 0.035 P

Chrome Cr:16.00 ~ 18

Ni Ni:12.00 ~ 16

Mo Mo:2.00 ~ 3

Corrosion resistance

316L because of its excellent corrosion resistance is widely used in chemical industry, 316L is belong to 18-8 type austenitic stainless steel are derived, add the Mo element 2 ~ 3%. On the basis of 316L, and derived a lot of steel, such as adding a small amount of Ti derived after 316Ti, add a small amount of N derived after 316N, increased Ni, Mo content derived 317L.

The market of the existing 316L most is in accordance with the American Standard to production. Because of cost considerations, steel mills generally the Ni content of the products as much as possible to lower limit on. American standard regulation, Ni of 316L content for 10 ~ 14% day marks the regulation, Ni of 316L content for 12 ~ 15%. According to the minimum standard, American Standard and Japanese standard 2% of the difference in the Ni content, reflected in the price is quite huge, so customers in the purchase of 316L products still need to see, the product is according to ASTM or JIS standard.

Mo 316L content makes this kind of steel has excellent resistance to pitting corrosion, can be safely used in containing Cl - and halogen ion environment. As the main application of 316L is its chemical properties, surface inspection of steel on the requirements of 316L was slightly lower (relative to 304), higher on the surface of the customer must strengthen the surface inspection dynamics.

316L - Mechanical Properties of tensile strength B (MPa): 480

The yield strength of sigma 0.2 (MPa): 177

Elongation of 5 (%): 40

Section shrinkage (%): = 60 PSI

Hardness: = 187HB; = 90HRB; = 200HV

Hardness is less than or equal to 187HB = 90HRB = 200HV

Q:Water and electricity thin wall stainless steel tube 304 material delta 2 what does that mean?
304 stainless steel is a universal stainless steel material, antirust performance than the 200 series of stainless steel material stronger.
Q:Does stainless steel pipe belong to hardware?
It belongs to me. Stainless steel pipe belongs to the category of hardware in the steel, and stainless steel pendants, flat iron is more hardware. All belong to steel alloy.
Q:What does "stainless steel pipe 201304" mean?
304 is a versatile stainless steel which is widely used in the manufacture of equipment and parts requiring good overall performance (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 18% chromium, more than 8% of the nickel content. 304 stainless steel is a brand of stainless steel produced according to the ASTM standard in the United states.
Q:Stainless steel pipe is mainly used in what areas?
According to the use of stainless steel pipe can be divided into oil well pipe (casing, tubing and drill pipe etc.), line pipe, boiler tube, mechanical structure, hydraulic prop pipe pipe, cylinder pipe, geological pipe, chemical pipe (high pressure fertilizer pipe, oil cracking tube) and shipbuilding pipe etc..
Q:Mirror stainless steel tube 60*60 how much is one meter?
Stainless steel tube square weight formula: (pipe circumference / 3.14- actual thickness) * actual thickness *0.02491* length, 0.02491 of which is converted by the stainless steel density of a constant.
Q:Is galvanized steel pipe stainless steel pipe?
No, the steel pipe is generally divided into stainless steel pipe, welded steel pipe, spiral steel pipe, low alloy steel pipe and so on.
Q:Stainless steel pipe welding interface leakage, how can we not leak?
Only when the welding quality is improved and the welding defects are reduced can the welding seam position be watertight:Argon arc welding is preferred for stainless steel pipe welding. When the wall thickness is thicker, the backing argon arc welding shall be used preferentially, and the filling and cover surface shall be welded by manual arc welding;The cleaning work before welding should be done well, and all the defects such as burr, oil stain, dust and spot welding should be removed;
Q:What are the weld sleeves for stainless steel pipes?
The process is the same as you set for the pipe welding material quota, stainless steel drop can, on the line in the budget when a show
Q:Stainless steel tube, also known as why tube
The longitudinal section can be divided into equal section tube and variable cross section tubeThe variable section tube has a conical tube, a stepped tube and a periodically cross section pipe, etc.
Q:What color is stainless steel? What color is stainless steel pipe culture?
Stainless steel is usually silver, also has colored stainless steel
