AISI 4330V Hollow Bar Forging , Downhole / Drilling Rig Equipment Anti - Corrosion

AISI 4330V Material Bar, Hollow Bar Forging for High Strength Drilling Components


Modified 4330V bar or hollow bar for high strength components possesses good fracture toughness. This material is generally not suitable for sour service. Products containing load bearing parts manufactured to this specification should be not used in installed sour service applications.


Melt Practice and Condition

The steel shall be electric furnace melted and refined using practices capable of producing fine grained materials free from deleterious defects.


The materials shall be supplied in the quenched and tempered condition and shall be free from excessive banding. The minimum reduction ratio during forging shall be 4:1 except where solid bar is supplied greater than 240mm (9.5’’) diameter, in which case the minimum forging ratio shall be 2.5. The minimum tempering temperature shall be 580°C(1076°F).


Chemical Analysis

The chemical composition shall be determined in accordance with ASTM A751 and shall meet the requirements in weight percent for the specific grade as listed in the table below.

Quality Requirements

The heat identification and heat treatment lot traceability shall be maintained through all stages of processing.


Surface shall be free from cracks, laps, seams and other surface defects.


Material certification shall be prepared for each heat and heat treat lot of material. Material certification shall be provided in accordance with BS EN 10204 Type 3.1. As a minimum, the certification shall contain the following: statement of compliance with this specification, chemical analysis results, mechanical test results, heat/heat treat batch identification and purchase order.
