Stainless Steel

Stainless Steel

Resists corrosion and chemicals in most environments

Steel

Strong, machinable, and weldable but lacks corrosion resistance

Aluminum

Lightweight, easy to machine, and corrosion resistant in wet environments

Glass

Clear and highly heat and chemical resistant; often used in sights, lighting, and lab equipment

Nickel

An upgrade from stainless steel that withstands harsh chemicals and acids at high temperatures

Fabricating and Machining
