Products is API 6A Flanges, Destructive test has been carriedout to verify on th finished flanges and found that impact is low. Hardness and Tesile exactly meet the requirements.
Can we check impact on actual parts.what is the better way to achieve impact of 42J at -42 deg by heattreatment.
How to achive yield strength of 85K , Tensile Strength of 105K and Impact of 42J average at -42 Deg c for 4130 Q& T materials.
Can we check the impact test in actual materials instead of QTC.
