1.3343 steel is the HSS type steel. HSS refers to high speed steel grade.1.3343 steel is a medium alloyed high speed steel with good cutting performance. The HSS 1.3343 steel chemical composition has good balance toughness, wear resistance and red hardness characteristics. Widely used in cutting tools such as twist drills, taps, milling cutters, saws, and tools. It is also commonly used in cold working presses and dies as well as in high speed and light cutting applications.
1.3343 steel has become the most widely used high speed steel to replace T1 grade high speed steel due to its superior performance and relative economy.
The 1.3343 steels available on the global market are as below:
-Flat bars
-Blocks
-Round bars
-Square bars
-Sheets

Heat Treatment of 1.3343 steel:
1.Soft annealing:
820 to 850 °C for about 2 to 5 hours
slow controlled cooling of 10 to 20 °C per hour to about 550 °C;
further cooling in air. Maximum 270 HB
2.Hardening:
1190 – 1230 °C
Quenching in oil/compressed gas/air/hot bath
obtainable hardness: 66 HRC
3.Tempering:
slow heating to tempering temperature (to avoid forming of cracks)
immediately after hardening;
triple tempering is recommended
