Metal & Steel
Gaskets & Materials

We manufacture gaskets onsite and produce custom-made products using our wide range of steel and metal materials.
Our range of steel and metal materials varies in terms of the type of finish, thickness, hardness and temperature tolerances.

Our Metal and Steel Material Range

Browse through the following list of popular metals and steels used for gaskets and other bespoke applications. If you are interested in a rubber material that is not listed below, contact us to discuss your requirements and the possibility of sourcing this for you.

Metal & Steel Material Options

Aluminum

Due to its excellent resistance to corrosion and easy handling it is very often used in manufacturing gaskets. Maximum service temperature: 460° C (860° F). Approximate Hardness: 35 HB.

Brass

Brass alloys can be excellent for machining, bending and folding. It is widely used for valves machined fitting and components for the plumbing, electrical, automotive, hydraulic, marine, gas and architectural industries.

Carbon (Mild) Steel

Material frequently used in manufacturing jacketed gaskets and ring joints. Due to its low resistance to corrosion it should not be used in water, diluted acids or saline solutions. Due to its excellent properties, mild steel has become an in-demand material in various industries. It has unparalleled weldability and machinability. Temperature limit 500° C (900° F). Approximate Hardness: 90 to 120 HB.

Copper

Material often used in small dimension gaskets, where the maximum seating stress is limited. Maximum operating temperature: 260° C (500° F). Approximate Hardness: 80 HB.

Inconel

Alloy with 77% Ni, 15% Cr and 7% Fe, it has excellent corrosion resistance from cryogenic to high temperatures. Temperature limit: 1100° C (2000° F). Approximate Hardness: 150 HB.

Stainless Steel

AISI 304

Alloy with 18% Cr and 8% Ni is the material most used in the manufacturing of industrial gaskets due to its excellent resistance to corrosion, low cost and availability in the market. Its maximum operating temperature is 760° C (1400° F). Due to stress and intergranular Corrosion, its continuous service temperature is limited to 420° C (790° F). Approximate Hardness: 160 HB.

AISI 304L

It has the same resistance to corrosion as the AISI 304. Since its carbon content is limited to 0.03%, it has less intergranular carbon precipitation and therefore less intergranular corrosion. Its operational limit for continuous service is 760° C (1400° F). It is susceptible to stress corrosion. Approximate Hardness: 160 HB and in some cases,140 HB.

AISI 316

This alloy with 18% Ni, 13% Cr and 2% Mo, offers excellent resistance to corrosion. It can have carbonate precipitation at temperatures between 460° C (860° F) and 900° C (1650° F), under severe corrosion conditions. Maximum recommended temperature for continuous service is 760°C (1400° F). Approximate Hardness: 160 HB.

AISI 316L

It has the same chemical composition as the AISI 316 but its carbon content is limited to 0.03%, which inhibits the Intergranular carbon precipitation and consequently, the intergranular corrosion. The maximum service temperature is 760° C (1400° F). Approximate Hardness: 160 HB.

AISI 321

Austenitic stainless steel alloy with 18% Cr and 10% Ni stabilised with Ti, which reduces the intergranular carbon precipitation and also the intergranular corrosion. It can be used in temperatures up to 815°C (1500°F). Approximate Hardness: 160 HB.

AISI 347

Alloy similar to the AISI 304 stabilised with Cb and Ta to reduce carbonate precipitation and intergranular corrosion. It is subject to stress corrosion. Has good performance in high temperature corrosive service. Maximum temperature: 815° C (1550° F). Approximate Hardness: 160 HB.

Titanium

Metal with excellent corrosion properties in elevated temperatures, oxidant service, Nitric acid and caustic solutions. Temperature limit: 1100° C (2000° F). Approximate Hardness: 215 HB.

Carl Quarterman

Owner and Managing Director

After earning a bachelor’s degree in Chemistry, Carl began his career working for BP as an Industrial Chemist before progressing through the company to become a supply chain specialist. For over 14 years, he operated extensively in the global business, focusing on supply chain management and integration.

His devotion to becoming a world-class leader started during his service in the Army Reserve, where he developed a particular interest in Australia’s Defense capability.

After serving on the Management Committee, Carl was elected President of the Australian Industry Defence Network (AIDN), Queensland in 2016 and has since contributed to and supported the AIDN National Executive, cultivating a strong relationship with Defence Jobs Queensland.

With strong leadership skills and global corporate experience, Carl took up the Queensland Gasket reins in 2012. Since then, the company has continued to work closely across industries utilising his supply chain network, as well as adapting to meet the changing needs of consumers, technologies, and business opportunities.
