2)AISI M2 steel should be free of heavy scale,deep pitting,laps,porosity,injurious segregations,excessive nonmetallic inclusions,seams,cracks,slivers,scale marks,dents,soft and hard spots,pipes or any defects that would detrimentally affect the suitability of T11302 steel.
3)Visual examination for M2 hss steel shall be made to ensure compliance with the requirements for workmanship,finish,dimensions and tolerances,identification marking and packaging.
The permissible deviation of T11302 hss steel shall not exceed 3mm in 1000mm length.This applies also to bars under 1000mm in length.Measurement is taken on the concave side of M2 high speed steel with a straight edge.
AISI M2 high speed steel annealed hardness values when obtained in accordance with the latest issue of test methods and definitions A370 shall not exceed 255 Brinell.
The hardness of T11302 high speed steel after the specified heat treatment shall meet the rockwell hardness of Min63HRC without showing any sigh of over heating.The hardness values when obtained in accordance with the latest issue of test methods and definitions A370 and shall be the average of at least 05 readings taken in an area midway between the center and surface of the largest dimension of the cross-sectional specimen or along the parallel surface of the longitudinal specimen.
1)Preheat M2 steel to Temperature 850°C;
2)Quench in salt bath at 1250°C or in controlled atmosphere furnace at 1260°C.
3)After being austenized for the proper time,T11302 steel may be oil quenched or quenched in Molten salt plus air cooling.
4)when a salt quench is employed,its temperature should be 560°C to 630°C.
5)Ultrasonic Test Report.
