20# steel is carbon steel with carbon content of about 0.20%. It belongs to low carbon steel with high quality. The equivalent material of 20# steel is S20C. 20# steel has low strength and hardness, good plasticity and toughness, good carburizing effect and good weldability. 20# steel is often used to make pressure parts (such as gasket, chain piece), carburizing parts (gear, CAM), welding parts, plastic mold, etc.
Other heat treating options include homogenizing, natural aging and precipitation hardening (which is essentially an artificial aging process). What is vibration stress relief? Manufacturers have more options than heat treating to relieve stress in aluminum alloys. One of the popular methods is known as vibratory stress relief.

Astro Aluminum Treating Co Check and Straightening. Solution heat-treatment of aluminum alloys often results in some distortion of the material. Astro has a 12,000 square foot work cell that offers a full range of check and straightening capabilities to return your material to its original form after the heat treat process is completed.
Aluminum Heat Treating develops the maximum amount of solute into solid Aluminum Solution Heat Treating. Aluminum alloys are classified as either heat treatable or not heat treatable, depending on whether the alloy responds to precipitation hardening. In the heat treatable alloy systems like 7XXX, 6XXX, and 2XXX, the alloying AMSH6088C: Heat Treatment of Aluminum Alloys - SAE International This specification covers the requirements and recommendations for the heat treatment of aluminum alloy rolled, extruded, forged, drawn, and cast product (See 6.1 and 6.5.1). It does not cover the requirements for the heat treatment of aluminum alloy parts (See 3.4). Subjects covered are: process es Types of Aluminum Heat Treatments - L&L Special Furnace Co, Inc. Aluminum heat treatment is a process by which the strength and hardness of a specific subset of aluminum alloys, namely the wrought and cast alloys that are precipitation hardenable, are increased. Precipitation hardenable aluminum alloys include the 2XXX, 6XXX, 7XXX and 8XXX series.
However, the solution treatment of the heat treatable aluminum alloys is conducted extremely close to the liquidus temperature of the aluminum alloy, and can very easily be subjected to l surface grain boundary melting. So residence and temperature selection are critically important to the thermal processing of the heat treatable aluminum alloys.

While the benefit of T6 heat treatment is accepted, the additional cost and production time associated with such a heat treatment are substantial. Considering the whole production cycle of a standard automo tive aluminium alloy wheel made by a low-pressure die-casting process (LPDC), the casting process normally takes less than 6 min,
Upon precipitation heat treating after quenching at the extrusion press, these alloys develop strengths nearly equal to those obtained by adding a separate solution heat treating operation. Changes in properties occurring during the precipitation treatment follow the principles outlined in the discussion of solution heat-treated alloys. Heat treatment of aluminum Part II | Thermal Processing heat treating of aluminum alloys Heat Treating Aluminum Alloys Aluminum alloys are classified as either heat-treatable or not heat-treatable, depending on whether the alloy responds to precipitation hardening. In the heat-treatable alloy systems such as 7XXX, 6XXX, and 2XXX, the alloying elements show greater solubility at elevated temperatures than at room temperature. Heat treatment of aluminum Part I: Quenching basics heat treating of aluminum alloys For most specifications used for aluminum heat treating, the delay time is measured from the time the furnace door is first opened, or the first portion of the load emerges from the salt bath, or the heating zone of a continuous, to the complete immersion of the load in the quenchant.
Heat treating for aluminum are precision processes. They must be carried out in ovens/furnaces properly designed and built to provide the thermal conditions and temperature uniformity required. To insure the final desired characteristics, process details must be established and controlled carefully for each type of product. Heat Treating of Nonferrous Alloys | Handbooks | ASM heat treating of aluminum alloys Volume 4E examines the heat treating process as it applies to nonferrous metals and alloys. It covers aluminum, copper, nickel, and titanium in detail, describing accepted heat treating practices and how they drive metallurgical transformations that ultimately determine material properties.
