Material Grades
API and proprietary steel grades for OCTG applications including carbon, alloy, and corrosion-resistant alloys with mechanical properties and specifications.
K55 Grade
Entry-level API grade for shallow wells and low-pressure applications with minimum yield strength of 55 ksi.
J55 Grade
Standard carbon steel grade widely used for general casing and tubing applications in conventional wells.
N80 Grade
Higher strength normalized grade available in Q (quenched) and T (tempered) variants for deeper wells.
L80 Grade
Sour service grade with controlled hardness for H2S environments requiring SSC resistance per NACE MR0175.
L80-9Cr Grade
Chrome-enhanced sour service grade with 9% chromium for improved CO2 corrosion resistance.
L80-13Cr Grade
Martensitic stainless steel with 13% chromium for superior CO2 corrosion resistance in production tubing.
C90 Grade
High-strength sour service grade for demanding environments requiring both strength and SSC resistance.
T95 Grade
Premium sour service grade with 95 ksi yield strength for deep wells with H2S and high pressures.
P110 Grade
High-strength grade for deep wells requiring maximum yield strength for collapse and burst resistance.
Q125 Grade
Ultra-high-strength grade for extreme depth and pressure applications requiring 125 ksi yield strength.
CRA Materials
Corrosion-resistant alloys including duplex, super duplex, and nickel alloys for extreme corrosive environments.
Chrome Series
Family of chrome-enhanced grades from 9Cr to Super 13Cr for tailored corrosion resistance.
