Note 1:For methods of estimating atmospheric corrosion resistance of low-alloy steels, see Guide G101. 1.3 When the steel is to be welded, it is presupposed that a welding procedure suitable for the grade of steel and intended use or service will be utilized.
CORROSION-RESISTANT HIGH-STRENGTH LOW-ALLOY Low-alloy steels having five to eight times the atmospheric corrosion resistance of carbon steels, 80,000 psi minimum yield strengths and an overall desirable balance of mechanical properties produced directly off the hot-mill have the following chemistry:carbon, .04 percent to .10 percent; manganese, .40 percent to 1.80 percent; sulfur, .03 percent maximum; aluminum, .015 percent minimum; chromium,
The steel with best corrosion resistance was selected, and then focused on the variation of its corrosion rate with time. The results indicated that the designed Cu-Cr-Ni low alloyed steels showed better corrosion resistance than 20MnSi, the ratio of their corrosion rates was 0.44.

MartensiticFerriticAusteniticIn general, martensitic stainless steels are considered moderate when it comes to corrosion resistance. Like low alloy or carbon steels, martensitic stainless steels are similar in structure to ferritic, but can be hardened or strengthened by heat treatmentwhich can also make them more brittle. This is due to the addition of carbon. The main alloying element of this family is chromium. The oil industry is a heavy user of martensitic stainless steel, as is the medical fieldprimarily for surgical equipment. Among the most Recommended corrosion resistant alloys for oil and gas wellsStainless steel, nickel alloys and nickel based alloys are widely used in the oil and petroleum refining industries for offering excellent corrosion resistance in aqueous, gaseous and high temperature conditions for their good mechanical characteristics at the entire range of temperatures from cryogenic to the high limits and are prominent for their special physical features.
Corrosion-resistant Alloys - Characteristics and UsesLow alloy steels are less susceptible than high alloy steels, but they are subject to SCC in water containing chloride ions. Nickel-based alloys, however, are not effected by chloride or hydroxide ions. An example of a nickel-based alloy that is resistant to stress-corrosion cracking is Inconel. Properties of Corrosion-resistant Alloys
few percent or less to produce high strength low-alloy (HSLA) steels. In some circumstances, the addition of 0.3% copperto carbon steel can reduce the rate of rusting by one quarter or even by one half. A modern and comprehensive document on the subject is the second edition of the classic CORROSION BASICStextbook.

US3787250A - Corrosion-resistant high-strength low-alloy Low-alloy steels having five to eight times the atmospheric corrosion resistance of carbon steels, 80,000 psi minimum yield strengths and an overall desirable balance of mechanical properties produced directly off the hot-mill have the following chemistry:carbon, .04 percent to .10 percent; manganese, .40 percent to 1.80 percent; sulfur, .03 percent maximum; aluminum, .015 percent minimum
Jun 12, 2016 · Atmospheric zone corrosion Low alloy steels demonstrate greatly improved resistance to marine environments compared to the resistance of C steels. The first indication that composition affects corrosion behaviour has been the observation that Cu bearing steels show improved endurance in industrial environments.
