Wellhead's Material

Wellhead's Material

(OP)
What the materials (ASTM or AISI) that generally use for casing head housing  (refer to API 6A-75k-AA Class)?

RE: Wellhead's Material

API has very few requirements on the chemical analysis of the steels used in these products.

In general, however, 4130 is used.  Slight variations may be used by specific manufacturers, but most of them are 4130.
