At Associated Steel, we pride ourselves on offering an in-depth selection of alloy steels. These materials include hot roll heat treated, cold finished annealed, turned ground and polished, heat treated hollow stock, and custom manufactured wear “rails”.
is a modified 4140/4150 alloy. It is offered in the hot roll, heat treated condition. Typical hardness is Rockwell “C” 28/34. Typical tensile strength 156,000 PSI. This proprietary product provides elevated strength and deep uniform hardness, excellent cleanliness, and refinement to the grain structure to enhance the fatigue resistance of the steel. Good choice of steel for machined parts requiring higher resistance to toughness and general impact resistance.

Kromite® #3 Hollow Bar
is a modified 4140/4150 alloy. It is offered in the hot roll, heat treated condition. Typical hardness is Rockwell “C” 28/34. Typical tensile strength 145,000 PSI. Offers all the same mechanicals as the solid bar but offered in heavy hollow stock for sleeves, wear rings, bushings and dies.
is a modified 4140/4150 alloy. It is offered in the heat treated, TGP condition. Typical hardness is Rockwell “C” 28/34. Typical tensile strength 156,000 PSI. This is a “near” bearing-fit shaft. Good choice of steel for machined parts requiring higher resistance to fatigue, toughness and general impact resistance. It is offered stress relieved, machine straightened and has a precision finish of RMS 15.
English and Metric TGP Rounds
is a modified 4140 alloy. It is offered in the cold finished annealed condition. Typical hardness is Rockwell “C” 19/24. Typical tensile strength 114,000 PSI. Its wear resistant properties far exceed that of “cold roll” steels. Offers an excellent upgrade in applications where 1018, 1020, 1045 and 1060 carbon steels are being utilized. Single largest selection of cold drawn alloy shapes in one location in North America.
Squares, Flats, and Hexagons
is a custom manufactured, precision “wear” component. Hardness range from Rockwell “C” 38/42 to 55/62 depending upon application. It is suited to handle many applications that are found in various industries including automotive, food processing, material handling, major appliance, and large manufacturing. Specific applications include transfer rails, “NC” blocks, guide rails, machine ways and various OEM parts.
Squares and Flats
is a modified 4140 alloy plate product that is 100% decarb-free and blanchard ground top and bottom (+.015”/+.035” oversize) for final clean-up. Typical hardness is Rockwell “C” 28/34. All products are produce from saw cut plate.
Squares and Flats
Kromite® Threaded Bar
is a modified 4140 alloy. It meets ASTM A193, Grade B7 standards. It is creep resistant, heat treated, and manufactured as roll threaded bar. Threaded rods that are rolled instead of cut are smoother and have less surface imperfections. Typical tensile strength 155,000 PSI.
