No, the steel used in bicycle frames comes in several alloys. ANSI 4130 (aka "chrome-moly") is a popular alloy. Reynolds "531" was a manganese-molybdenum alloy, but is more suitable for low temperature brazing than modern automated TIG welding, and is no longer generally available. Reynolds "953" tubing is a stainless alloy optimized for TIG welding.
