Blasting absolutely can NOT cause hydrogen embrittlement. Blasting unevenly can cause thinner parts to warp and distort.

Mike,
In very broad terms, hydrogen embrittlement is the absorption of hydrogen atoms into the crystalline structure of a metal when it is immersed in a hydrogen-containing substance, such as hydrochloric acid. Hydrogen tends to accumulate and weaken the steel unless expelled by baking.
