A4 (AISI 316) grade stainless steel is a highly corrosive stainless steel that contains molybdenum. It has a higher Nickel content to that of A2 stainless steel.
This grade contains anti-corrosive properties making a great choice for marine applications.
The molybdenum content within this stainless, increases the corrosion resistance to withstand attack from industrial chemicals, chlorides and solvents.
This grade of stainless is also used in surgical environments, as it’s smooth surface and anti-corrosive properties makes it easy to clean.
A4 Stainless has long durability.
Here at Caleb Components, we can offer a wide range of our non-threaded fasteners in A4 Stainless Steel, including Circlips, E-Clips, Spring Tension Pins (Roll Pins) and Cotter Pins.
In modern engineering, standard materials like steel and aluminium often hit a hard physical limit. When temperatures soar past 500°C, or when corrosive acids threaten to dissolve equipment, regular metals weaken, deform, and fail.
Enter Inconel.
Inconel is a family of nickel-chromium-based superalloys specifically engineered to thrive in environments that would destroy ordinary metals. Here is a deep dive into why this material is indispensable to high-stakes industries worldwide.
What Makes Inconel a “Superalloy”?
The secret to Inconel’s power lies in its chemical formulation. Primarily composed of nickel and chromium, it also incorporates trace elements like iron, molybdenum, niobium, and titanium.
When exposed to extreme heat, Inconel undergoes a unique chemical reaction. Instead of breaking down, it forms a thick, incredibly stable passivating oxide layer on its surface. This layer acts as a permanent shield, protecting the rest of the component from further oxidation, corrosion, and thermal degradation.
Key Performance Benefits
Extreme Thermal Stability: Maintains its structural and tensile strength at temperatures exceeding 700°C (1,300°F).
Creep Resistance: Resists permanent mechanical deformation under continuous, high-stress loads over long periods.
Corrosion Immunity: Withstands aggressive chemical exposure, including saltwater, sulfuric acid, and hydrochloric acid.
Cryogenic Strength: Unlike steels that become brittle in freezing environments, Inconel maintains excellent ductility at sub-zero temperatures.
We can supply a wide range of products in this material, including Circlips and Disc Springs (Belleville Washers).
Inconel Materials we can offer:
Inconel 625
Inconel 718
Inconel X750

When it comes to protecting high-strength metal components, standard electro-zinc plating or heavy hot-dip galvanising eventually hit a wall. Traditional methods can introduce microscopic weaknesses, while heavy dipping can ruin the fine tolerances of precision parts.
Dacromet—a highly specialized, non-electrolytic zinc flake surface technology—replaces traditional methods by combining ultra-thin layers with brute-force corrosion resistance.
If you are manufacturing or specifying heavy-duty parts, automotive components, or high-grade fasteners, here is why Dacromet has become the global industrial standard.
Dacromet is not just a surface wrap; it is an inorganic coating composed of overlapping zinc and aluminum flakes bound together by a specialized matrix. This formulation gives it several distinct advantages:
1. Zero Hydrogen Embrittlement (The Fastener Lifesaver)
Traditional electroplating relies on acid pickling and an electrical current. This process inadvertently forces hydrogen ions into the metal matrix, causing high-strength steel bolts (Grade 10.9 and 12.9) to crack and snap unpredictably under tension. Because Dacromet is applied without electrolysis or acid, it eliminates the risk of hydrogen embrittlement entirely, making it the safest choice for critical load-bearing joints.
2. Extreme Salt Spray Endurance
Standard zinc plating offers about 200 to 300 hours of protection before red rust takes over. Despite being an incredibly thin layer (typically just 4 to 8 microns), a Dacromet coating withstands over 1,000 hours of neutral salt spray testing. That is up to 10 times the anti-rust performance of traditional options.
3. High Thermal Stability
Many defensive coatings peel, blister, or degrade when exposed to heat, rendering them useless in environments over 100°C. Dacromet remains completely stable and resists corrosion at continuous temperatures up to 300°C. This makes it perfectly suited for vehicle engine compartments, braking systems, and heavy industrial machinery.
4. Flawless Coverage on Mating Parts
Hot-dip galvanising leaves behind a rugged, thick, and uneven texture that easily clogs up internal threads. Dacromet is applied using a specialized dip-spin process. The liquid slurry flows evenly into deep recesses and fine thread pitches, then spins off excess material to guarantee a highly uniform matte-silver finish without ruining the part’s dimensions.
⚙️ How the Dip-Spin Process Works
Instead of floating ions onto the metal using electricity, the Dacromet technique relies on mechanical immersion and heat:
Mechanical Cleaning: Metal parts are shot-blasted or degreased without harsh acids to completely clean the substrate.
The Dip-Spin: Parts are placed into a mesh basket, submerged into the zinc-aluminum slurry, and spun at high speeds to centrifugally remove any excess coating.
Curing: The parts are baked in industrial ovens at roughly 300°C to 320°C. This heat fuses the metallic flakes together into an incredibly dense, overlapping shield.
🏎️ Where is Dacromet Used?
Because it thrives where salt, heat, and structural stress collide, you will find Dacromet coatings widely utilized across several sectors:
Automotive: Brake discs, calipers, leaf springs, and structural under-chassis fasteners.
Infrastructure: High-tension structural fasteners used in bridges, railways, and heavy construction.

Titanium circlips are the ultimate upgrade for high-performance engineering, offering an unparalleled strength-to-weight ratio and absolute corrosion resistance compared to traditional steel variants. Often referred to as retaining rings, these precision fasteners are engineered to sit inside a machined groove on a shaft or housing bore, using radial tension to keep components locked firmly in place under intense vibration. While standard spring steel is prone to rust and degradation over time, switching to titanium brings specialized benefits to elite automotive, aerospace, and cycling applications.
🔧 Where Are Titanium Circlips Used?
Because of their premium cost, titanium snap rings are reserved for elite mechanical environments where failure is not an option:
Motorsports: High-performance bikes like the Suzuki RGV250 or GSX-R600 rely on titanium external circlips to lock drive sprockets in place or secure drilled titanium brake pad pins.
Premium Cycling: Weight-conscious cyclists use titanium circlips and bolts on brake pad assemblies and bottom brackets to build sub-7kg setups.
Marine & Aerospace Hardware: Any application subjected to heavy saltwater exposure or extreme thermal cycling benefits from titanium’s inability to rust or degrade.
