Difference between 304 and 316 Stainless Steel
Both grades are austenitic stainless steel which is one of the most
widely used and versatile type of steel. As 304/304L stainless
steel plates & sheets have excellent corrosion resistance, 316/316L
plates have higher nickel content than 304 and 304L SS sheets
giving them even better corrosion resistance especially in marine
applications.
316/316L Stainless Contains Mo Provides better Resistance to High
Temperature
Refer to chemical composition 316 stainless steel contains element
Mo, which is the reason that 316/316L has better corrosion
resistance than 304/304L, especially in high temperature
conditions. Therefore, engineers usually choose 316 material in
high temperature environments. However, if the environment consist
sulfuric acid, do not use 316/316L for high temperature, as the
Molybdenum will be easily reacts to high-priced sulfur ions and
form sulfides.
321 Stainless Steel
Type 321 SS plates are a good choice for applications where heat is
an issue. 321 can be used in applications up to 900°C where 304L is
normally used up to 500°C.
Hot Rolling
Hot rolling for making the medium thickness plate from 4.5mm to
100mm.
Cold Rolling
Cold rolling for making a thin cold plate thickness of 0.02 to 4mm.
Heat Treatment
In order to ensure that the mechanical properties such as yield
strength, tensile strength, elongation and hardness of all kinds of
stainless steel plates meet the requirements, the steel plate must
be subjected to heat treatment such as annealing, solution
treatment and aging treatment before delivery.
316N, 316LN
316 or 316L after normalized will be 316N or 316LN, and it provides
better yield strength up to 320Mpa minimum (for thickness above
38mm).
And for thickness under 38mm, 316N yield strength minimum 550 Mpa,
and Tensile strength 240 Mpa; Correspondingly 316LN miniumu YS 515
Mpa, and TS 205Mpa.
Weight of 316 Stainless Steel Plate, Sheet, Coil
To calculate the weight of 314 stainless steel plate in kgs use the
formula: length (m) x width (m) x thickness (mm) x 7.93
