Metals For Every Application
We supply a comprehensive range of steel and alloy products, each engineered for specific performance in demanding environments. Explore the categories below to learn more about their unique characteristics and available grades.
⚙️
Alloy Steel
High-strength steels engineered for demanding applications
A steel alloy is created when other metals are added to the basic combination of iron and carbon, improving its properties. Looking for higher strength, corrosion resistance or better response to heat treatment? There's an alloy for that. When the percentage of alloy material is below the level indicated by specialized terms such as 'chrome' or 'stainless,' the product is simply called 'alloy steel.'
Key Characteristics
- Enhanced strength through alloying elements
- Improved heat treatment response
- Better wear resistance
Applications
- Drilling equipment
- Tubing and casing
- Mechanical components
Available Grades (6)

🔨
Carbon Steel
Versatile carbon steel grades for general applications
By definition, all steel is a mixture of iron and carbon. Steel to which no alloy elements have been added is called 'carbon steel.' It's been at least 4,000 years since people discovered that adding a controlled amount of carbon to iron created a new kind of metal — one that was strong, held a sharp edge and could bend without breaking. At Continental, we live and breathe specialized metallurgical chemistries. But at the end of the day, we think good old steel is still pretty exciting.
Key Characteristics
- Fundamental iron-carbon combination
- No specialized alloy additions
- Cost-effective material

Stainless Steel
Corrosion-resistant stainless steel for harsh environments
Stainless steel is alloy steel to which at least 10.5% chromium has been added, making the material stain-resistant. When corrosion resistance is a priority, you need stainless steel. Continental will analyze your working environment and supply the best and most cost-effective stainless alloy for the conditions. The combination of chromium, nickel and other elements can be tailored to any unique situation.
Key Characteristics
- Minimum 10.5% chromium content
- Excellent corrosion resistance
- Passivation layer provides protection
Applications
- Corrosive downhole environments
- Saltwater applications
- Chloride-containing atmospheres
Available Grades (4)

🛡️
Chrome Steel
Chrome-enhanced steels for oil and gas applications
These metals are used in mildly corrosive environments containing chlorides, carbon dioxide and low hydrogen sulphate concentrations. Chromium is a hard metal that adds corrosion resistance when alloyed with steel. Alone, it polishes to a mirror-like shine — that's why it's often used as decorative plating, where it's called 'chrome.' For oil and gas industry steel products, Continental adds varying quantities of chromium to molten steel to create the best and most cost-effective alloy solutions.
Key Characteristics
- Higher chromium content than alloy steels
- Improved corrosion resistance
- Cost-effective alternative to stainless
Applications
- CO2 environments
- Mildly saline conditions
- Low hydrogen sulphate exposure
Available Grades (3)

Nickel Alloys
Premium nickel alloys for extreme environments
Nickel alloys are extremely corrosion-resistant, even at very high strength levels. When customers ask for the ultimate in toughness and corrosion resistance, Continental answers with nickel alloys. Complex down-hole tools and lining or cladding for pipes, storage vessels, well-heads and assemblies are typical nickel applications. Nickel is weldable, and plays nicely with steel.
Key Characteristics
- Extreme corrosion resistance
- Superior toughness at high strength
- High-temperature capability
Applications
