Wear Products: Q&T Wear Plate

Quenched and tempered low alloy steel plate providing resistance to abrasion are:

	Hardness Range in Brinell Hardness	Tensile Strength (Typical) PSI	Yield Strength (Typical) PSI
Q & T 360	360 - 415	190,000	180,000
Q & T 400 / 400F	360 - 440	200,000	180,000
Q & T 425	400 - 477	200,000	180,000
Q & T 440F	415 - 477	200,000	190,000
Q & T 500	477 - 545	225,000	200,000

The ductility and toughness of these grades increases as hardness decreases. These wear plates are widely used for liners in the transporting and processing of material.

Maximum Thickness: 3"

Representative examples of this material would be Oregon Steel Mills' "formalloy", and Algoma Steel's "algoform".

Welding Procedures

Q & T plate products obtain high strength through a combination of rapid cooling and low alloy content, followed by various tempering temperatures. Low chemistry facilitates welding of all Q & T plate grades with simple procedures and common methods.

If the weld itself is not exposed to the wear environment, a low strength welding rod such as E7018 or E 7028 is recommended. Where the weld is exposed to abrasive mediums, the bulk of the joint can be filled with lower strength material and a capping layer of abrasion resistant material can be applied such as E8018, E10018 and E11018.
