RE: ASTM HK30 heat treatment

ASTM A 297 gr HK is the cast equivalent . This being a heat resistant steel any heat treatment is optional.

RE: ASTM HK30 heat treatment

You should have a copy of the appropriate material specification. ASTM A 351 Grade HK30 requires they be supplied by the manufacturer in the as-cast condition.

thanyou guys

a lot of the time even the customer is unsure of what specification they need, they just state the material and think we know all about it.

we,ll ask them about being supplied as cast.

cheers

lakk, our company cast niobium modified HK30 and our customer need this alloy in heat treated state. It is annealing. 1125C for not less than 2 hours in vacuum and subsequent cooling in furnace.
