304L Stainless Steel Corrosion Resistance - TP304L 1.4307

Stress Corrosion Cracking The Alloys 304, 304L, and 304H are the most susceptible of the austenitic stainless steel to stress corrosion cracking (SCC) in halides because of their relatively low nickel content. Conditions which cause SCC are:(1) presence of halide ions (generally chloride), (2) residual tensile stresses, and (3) temperatures in excess of about 120°F (49°C).

Corrosion Assessment:8 Corrosion Tests That Help Engineers

Feb 19, 2014 · Some test samples and procedures are designed to assess specific kinds of corrosion, such as crevice corrosion, stress-corrosion cracking, and erosion corrosion. The atmospheric corrosion of coated samples can be examined by salt spray or fog testing. Here, a 5% NaCl solution is atomized in a chamber at a temperature adjusted to 95°F (35°C). EVALUATION OF METHODS FOR IMPROVING MOTOR TUBE Corrosion testing of AGI hardened 410 stainless steel control rod drive mechanism motor tubes indicated that design stresses might not be achieved. The results of evaluation of several corrective design steps are given. (T.R.H.)

Effect of Microstructure and Mechanical Properties on the

The stress corrosion cracking (SCC) of the commercial austenitic stainless steel type 304 was investigated as function of test temperature, microstructure and mechanical properties in acidic chloride solution (25 wt.%-MgCl 2) using slow strain rate tests (SSRT).Susceptibility and mechanism of SCC was investigated using SSRT performed at strain rate of 1 x 10-6 in/s in a glass autoclave Effect of Residual Stress on the Corrosion Behavior of In this paper we demonstrate that the residual stress introduced by several different surface finishes affects the critical current density for passivation and the passive current density in the anodic polarization curve of austenitic stainless steel and that those critical current densities can be reduced by controlling the residual stress by applying a cavitating jet to the backs of specimens.

The samples exfoliated in the base metal, but did not exfoliate in the weld metal or Mechanisms of Stress-Corrosion CrackingStress-corrosion cracking (SCC) is a term used to describe service failures in engineering materials that occur by slow, environmentally induced crack propagation. The observed crack propaga­ tion is the result of the combined and synergistic interaction of mechanical stress and corrosion re­ actions. Before SCC can be discussed in detail, we
