Product & material range
Premium-grade tubular materials and precision-engineered products for the Oil & Gas industry — supplied in the grades, forms, and finishes your program needs.
API 5CT tubing and casing supplied to your well program — sized, graded, and inspection-ready for running downhole.
Seamless hollow sections in all supported grades — an efficient starting point for couplings, subs, and machined tubular parts.
Bored bar with controlled internal diameter, ready for finishing operations such as honing and turning through our network.
Part-machined tubular components supplied ready for your final operations — saving lead time on your shop floor.
Fully machined tubular components produced to drawing through Apollo's approved finishing partners — boring, honing, and turning to tolerance.
Premium steel raw materials held in strong inventory and selected for durability, performance, and compliance with industry requirements.
Seamless martensitic 13% chromium tube for precision downhole and mechanical use — dependable CO₂ corrosion resistance held to tight dimensional tolerance.
A 25% chromium super-duplex alloy for the harshest wells — high-chloride, high-CO₂ and sour service where standard tubular grades reach their limit.
A 28% chromium high-alloy grade for extreme corrosive duty — outstanding resistance to pitting, cracking and hot-chloride attack in critical sour environments.
Solid round and hollow bar across the full grade range — from AISI 4140 through 25/28 Cr — supplied ready for turning, boring and finishing into precision components.
Raw materials & steel grades
We maintain a strong inventory of premium-quality steel suitable for demanding oilfield applications. Each grade is available as hollow bars, bored bars, tubular components, and semi-finished products.
| Grade | API | Min. yield | Key property | Typical service |
|---|---|---|---|---|
| AISI 4140 — 80 KSI | L80 | 80,000 psi | Balanced strength & toughness | Standard wells; mildly sour service |
| AISI 4140 — 125 KSI | P110 | 125,000 psi | High strength for deeper sets | Deep, high-pressure wells |
| 13 Cr | 13 CR | 80–110 KSI | CO₂ corrosion resistance | Wet CO₂ / mildly corrosive gas |
| Super 13 Cr | S13 CR | 95–125 KSI | Enhanced CO₂ + limited H₂S tolerance | Aggressive sour & high-CO₂ service |
| 25 Cr | 25 CR | 110–125 KSI | Super-duplex — high pitting resistance | High-chloride sour & high-CO₂ wells |
| 28 Cr | 28 CR | Grade-dependent | High-alloy — extreme corrosion resistance | Severe sour & hot-chloride service |
Yield values are indicative of grade class; certified mechanical properties are provided per heat with material documentation.
