Properties of A1008 Steel

A1008 is a standard specification for cold rolled, carbon steel. The process of cold rolling the steel creates a smooth surface which is typically oiled to prevent surface rust from forming. Compared to hot rolled steel, A1008 is known for having excellent weldability and formability. The cold rolling process also creates good drawing and spinning characteristics and a steel that works well in most common steel processing options. Chemical Composition: Carbon 0.15% (Max); Manganese 0.60% (Max); Phosphorus 0.030% (Max); and Sulphur 0.035% (Max)

 

Typical Uses of A1008 Carbon

Because steel  is a durable, versatile material, it is used in a wide range of structures and applications including construction, framing, ductwork, machinery framing, and many other industrial applications. As a material A1008 is typically used in applications where it will not be exposed to elements due to potential for aging. The surface is usually oiled to help reduce aging. Cold rolled steel is often selected for applications like truck beds, truck cab backs, and areas not exposed to the elements that require strength. A1008 is
typically bought to meet chemistry requirements rather than
physical requirements. For that reason, physical properties are
generally not provided unless requested prior to production. Any
material can be sent to a third party after production to be
tested for physical properties.

About Cold Rolled Steel

Cold rolling is a processing technique that presses metal through rollers at temperatures below the material’s
recrystallization temperature. The process increases the yield strength and hardness of the steel, sometimes by as much as 20%
depending on the specific processes used. It can also reduce the
grain size of the metal, improve its surface finish, and hold
tighter tolerances. By keeping the material below the
recrystallization temperature, the metal becomes less malleable,
making cold rolling a labor-intensive process. It can also produce thinner steel than hot rolling.

Stainless Steel

304 Stainless Steel is the most popular and economical of the stainless steels. 304 Stainless Steelt offers good corrosion resistance to many chemical corrodents as well as industrial atmospheres and marine environments. 304 Stainless Steel may become slightly magnetic when worked and is not heat
treatable. Specifications: AISI 304/304L, ASTM A240, AMS 5513/5511. Applications: sanitary dairy, beverage and food product handling and processing, hospital equipment, marine hardware, kitchen appliances, back splashes, etc.

STANDARD MATERIALS

Operating temperature range: -20° F to 200°F. Can run up to 300°F for a very short time. Provides good resistances to most mineral oils, greases with a mineral oil base, gasoline, diesel, light heating oil, animal & vegetable oils & fats and hot water. NBR has poor ozone and impact resistance but has very good abrasion resistance. Standard is 75 durometer, H1 comes in 85 durometer.

Continuous operating temperature range: -10°F to 450°F. Can run up to 600°F for a very short time. Preferred for high temperature applications where rubber usually burns. Not recommended for applications where there is any contact with esters and ketones. Does not perform well in hot water. Standard is 75 durometer, H1 comes in 85 durometer.

Continuous operating temperature range: -30°F to 250°F. Can run up to 325°F for a very short time. Provides excellent resistance to heat, water and steam, alkali, ozone and UV rays. Not recommended for applications where there is any contact with gasoline, petroleum oil, grease and other such hydrocarbons. EPDM can withstand the effects of brake fluids. Standard is 75 durometer, H1 comes in 85 durometer.

Continuous operating temperature range: -40°F to 225°F. Can run up to 300° F for a very short time. CR is not recommended for use in aromatic mediums such as benzone or in oxygenated solvents. CR possesses good ageing characteristics in ozone and UV rays. CR also offers good impact and abrasion resistance.

Operating temperature range: -100°F to 400°F. High thermal expansion PTFE is chemically inert (resistant to hydrocarbon/oxygenate blends) and well suited to applications involving extreme operating conditions. Excellent dry running capabilities. Low coefficient of friction. Well suited for high speed applications where surface speeds exceed 6,000 feet per minute. Poor abrasion resistance.

Continuous operating temperature range: -20°F to 300°F. Can run up to 350°F for a very short time. Provides good resistances to most mineral oils, greases with a mineral oil base, gasoline, diesel, light heating oil, animal & vegetable oils & fats and hot water. HNBR has very good ozone resistance and possess good impact and abrasion resistance.

Operating temperature range: -50°F to 200°F. Good choice for low temperature operations. Good dry running capabilities. Poor heat resistance.
