Stress Corrosion Cracking

In halogenated environments, austenitic stainless steels are susceptible to stress corrosion cracking. Although $number, 317L has a better corrosion-resistant cracking resistance than 18cr-8ni alloys due to its molybdenum content, they are still relatively susceptible to damage.

The Conditions for Producing Stress-corrosion Cracking include:

(1) The existence of halides (generally chloride),

(2) residual tensile stress,

(3) temperature exceeding 120°F (49°C).

During the welding process, the stress can be produced by cold deformation or thermal cycling. Annealing, stress-relieving heat treatment can effectively reduce stress, thus reducing the sensitivity of materials to halide stress corrosion cracking. The l grade of low carbon has no special advantage in the stress corrosion cracking, but the L grade is still preferred in the condition of stress elimination, because it can cause intergranular corrosion in this environment.


316, 317L has good oxidation resistance, in the atmosphere, even if the temperature reaches 1600 to 1650°F (871 to 899°C), rust skin production rate is also relatively low. In general, 316 performance slightly more than 304 stainless steel, because 304 chromium content slightly higher (18%, 316 chromium content 16%). The oxidation rate is usually affected by the atmosphere and the operating environment, so the exact oxidation rate is not available for reference.

Physical Properties Structure

After proper annealing, the 316,317 alloy is mainly austenite. A small amount of ferrite may appear. When cooled from 800 to  1500°F(427 to 816°C), the carbide precipitates, which are composed of austenite and carbide structure.

Density: 0.29 lb/in3 (8.027 g/cm3)

Tensile modulus of elasticity: 29 x 106 psi (200 Gpa)

Shear modulus: 11.9 x 106 psi (82 Gpa)

What's the difference of 304 stainless steel plate and 316 stainless steel plate

304 stainless steel plate and 316 stainless steel plate are now the most common two kinds of stainless steel plate. Both kinds of stainless steel species are stainless steel containing molybdenum elements. The amount of molybdenum in 316 stainless steel plates is higher than that of 304 stainless steel plates. Because of the molybdenum element in the steel plate, the overall function of the two kinds of steel plate is higher than 310 and 317 stainless steel plate. At a certain temperature, when the concentration of sulfuric acid is not higher than 15% or above 85%, 304 stainless steel plate can be widely used. In addition, the steel plate also has excellent corrosion resistance and can be used as usual in marine situations.

The difference in carbon content: 304 stainless steel plate can be allowed to the highest level of carbon is 0.03, 316 stainless steel plate with the highest content of carbon is higher than 0.03. Carbon content in the welding after the method of annealing has some help, can improve corrosion resistance.

The difference in erosion resistance: 316 stainless steel plate corrosion resistance is slightly better than 304 stainless steel plate, in the day-to-day use has a prominent erosion resistance. Another 316 stainless steel plates can withstand the heavy corrosion of industrial waste gas.

The difference in heat resistance: under 1600 degrees and 1700 degrees of high temperature, can continue to use 304 stainless steel plate, 304 stainless steel plate strong oxidation resistance played a decisive role; in the 800-1575 degree this interval, it is best not to use 316 stainless steel plate, However, at this temperature of 316 stainless steel continuous use, then 316 will have a prominent high temperature resistance. Mainly because the two contain MO element difference, 304 content is less.

The difference in heat disposal: the stainless steel plate is annealed at 1850-2050 degrees in this temperature interval, then the agile annealing process is performed, then the agile cooling process is processed. 316 stainless steel plate can be done by means of overheating treatment and hardening, and 304 can only at a slightly lower temperature treatment.

Welding Performance difference: 304 stainless steel plate itself has excellent weldability. The steel plate can be welded by any standard welding method. Can be used according to the needs of the use of different welding electrodes. In order to obtain the most excellent corrosion resistance, 304 stainless steel plates need to be annealed and disposed of the steel plate during the welding section. and 316 stainless steel plate, do not need to be treated by annealing can.
