||Workshop Will Explore Stress-Corrosion Cracking
ASTM Committee G01 on Corrosion of Metals is organizing events on stress corrosion
cracking (SCC) to be held Tues., Nov. 6, during their biannual
meetings in Dallas, Texas, Nov. 7-9.
A morning workshop, Design Criteria for Controlling Stress Corrosion
Cracking, will be followed by an afternoon discussion of SCC
issues between attendees and a panel of experts. There is no admission
charge, but pre-registration is requested of those wishing to
make a presentation or address the panel.
Part of a series developed by Subcommittee G01.06 on Environmentally
Assisted Cracking, the workshop will focus on SCC problems in
the petroleum, pipeline, refining, and chemical industries. Subcommittee
chairman Russell D. Kane, Ph.D., InterCorr International, Inc.,
Houston, Texas, said workshop topics will include:
Problems associated with cracking of steels in hydrogen sulfide
Cracking in stainless alloys in hot chloride-containing media;
Hydrogen cracking of high strength bolting materials; and
External SCC of pipeline steels.
In the afternoon session, the audience can pose problems to the
panel and discuss potential solutions.
The cost of corrosion in the petroleum, pipeline and chemical
industries has been estimated to be approaching $30 billion annually
in the United States alone, Kane said, citing information from
Corrosionsource. com. Stress corrosion and related cracking phenomena
are significant factors in these costs. SCC is a major factor
in unexpected, catastrophic failures in pressurized equipment,
resulting in increased operational risk, potential high dollar
loses, and loss of life. As interest in high strength materials
expands, the risk of cracking generally increases and better specifications
are needed to minimize problems from SCC, Kane said.
ASTM Subcommittee G01.06 on Environmentally Assisted Cracking
will address needed standardization in this area. Activities under
way involve stress corrosion cracking, hydrogen embrittlement,
high temperature hydrogen damage and procedures for evaluating
stainless steels, and aluminum and copper alloys.
All are encouraged to attend these events, as well as G01 subcommittee
or task group meetings on Nov. 7.
