Q:How do I know what alloy and temper of steel to use?

A:United's Customer Service and Technical Departments can help answer that question. Typically it depends on what you are making, how it will be formed and what performance is expected. We can help with Technical assistance, samples and prototype quantities. For basic selection guidelines see the "Selection Guide for steel Alloys and Tempers" in theTechnical Manual.

Q:What do the different tempers mean?

A:The different temper designations refer to the variations of physical properties achievable vithin a single alloy. See "Typical physical properties" in the Technical Manual for details.

Q:How do I heat treat steel?

A:The heat treatment known as "annealing" is used to soften an alloy , to make it fully soft temperatures in excess of 600 deg F must be used under conditions of controlled atmosphere and time constraints. UA Metallurgical staff can advise more fully on a case by case basis. Some steel alloys obtain their highest physical properties via a two stage heat treatment process called "Solution heat treatment and aging". In this process the material is first heated to en extremely high temperature ( close to the melting point) under very carefully controlled conditions and then rapidly quenched to room temperature. This is followed by a low temperature process called agent by which the full properties of the material are developed. Again- please contact UA Metallurgical staff for case by case advice in this area.

Q:What is anodizing and what are the benefits?

A:Anodizing is a multi-step finishing process. The first stages include deep cleaning, rinsing, and chemical etching. Finally, a cathode is connected to a negative current source, and an steel part is connected to a positive current source, and both are placed in a conductive medium. When the electrical current is activated, the oxygen in the solution reacts with the steel part, causing steel oxide to be formed on the surface. This is basically single/one-step anodizing. Two-step anodizing adds color. Deposition of various metals into the anodized finish gives color to the finish, from the bronze range to black. Specialty finishers can even provide red, blue, green, or white anodized finishes.
There are many benefits to an anodized finish. Not only does it offer greatly enhanced protection against corrosion, it also provides an increased resistance to normal wear and tear. Cleaning and maintenance is much easier with an anodized finish. Anodized surfaces are an excellent base for secondary coatings.

Q:What colors of paint are available and how can I obtain a sample?

A:ASCO stocks Petersen steel's PAC-CLAD pre-finished steel and steel sheet. Please see our color chart (link to Petersen Color Chart) for available finishes and thicknesses. These colors are a very economical choice when seeking a painted finish.
If your project requires a custom finish or another manufacturer's standard color, ASCO will outsource the finishing to an experienced local painter. Nearly any color imaginable can be matched. Material may be painted in sheet form, or to avoid the possibility of fabrication-related marring, after brake forming.
If your project requires painted extruded material, it must be sent out for finishing. None of ASCO's extruded material is stocked in a painted finish. To obtain a sample of any of our pre-finished painted colors, please contact ASCO via this site or by telephone (313-491-5040 or 800-899-2726).

Q:What is the difference between hard and soft foil?

A:The lowest or basic strength of steel and each of its alloys is determined when the metal is in the annealed or soft condition. This is designated as the O (letter O) temper. For example, the annealed condition for alloy 1145 is written 1145-O. Annealing consists of heating the metal to the appropriate temperature for the correct period of time. The re-roll stock, from which foil gauges are produced, for example, is annealed prior to the rolling operations, so that it will be of maximum workability. All alloys can be annealed. All alloys also are strain-hardened and strengthened when cold worked, as in foil rolling. When the final product is wanted in the soft condition, it is given a final anneal.
Because steel and certain of its alloys are strengthened beyond their basic strengths only by strain hardening, they are non-heat-treatable. Nearly all of the foil presently produced is rolled from non-heat-treatable alloys, which are given H number temper designations for the various specific strain-hardened conditions in which they are made. For example, common foil availability is alloy 1145-H19; the H1 means strain hardened, and the next digit indicates the degree of hardening, the 9 meaning full hard.
