O1 OIL HARDENING TOOL STEEL ANNEALING Heat slowly and uniformly to 1140°F; soak thoroughly and then allow to cool slowly in the furnace to below 1000ºF. STRESS RELIEVING When heavy machining cuts are employed the resultant stresses may be relieved by heating the material to 1200 -1250°F for one hour and cooling in still air.

O1 steels can be easily formed in the annealed condition using conventional methods. O1 steels should be heated uniformly to 780-820°C (1436-1508°F) until completely heated through. If needed, the steels can be preheated at 300-500°C (572-932°F).

ASTM O-1 tool steels should always be annealed after forging. 6. AISI O1 Tool Steel Heat Treatment. Annealing must be performed after hot working and before re-hardening. Heat at a rate not exceeding 222°C per hour to 802-816°C, and hold at temperature for 1 hour per inch (25.4mm) of maximum thickness; 2 hours minimum.

In order to anneal steel, you’re going to need a way of heating up the metal until it’s bright red, hold it at that temperature for a while, and then very slowly allow it to cool. There are two main approaches to this: using a torch, forging furnace, or other non-regulated source of heat, or using a programmable heat treating oven.

2015年4月8日 · Re-annealing will only be necessary it the steel has been forged by the tool maker. To anneal, heat slowly and uniformly in a closed box or tube to 740/760 degrees centigrade. Maintain at the temperature and allow to cool with the furnace until the temperature falls below 500 degrees centigrade.

2012年5月2日 · Bandsaw and hacksaw with bi-metal blades are fine for cutting stock to length. Filing works for shaping, but the O1 will harden from the heat generated. A bench grinder is better--dip the work in cool water frequently while grinding. If O1 does harden while working, you probably can't anneal it without a digitally-controlled oven.

Annealing. Annealing must be performed after hot working and before re-hardening. Heat at a rate not exceeding 400°F per hour (222°C per hour) to 1425 -1450°F (802-816°C), and hold at temperature for 1 hour per inch (25.4mm) of maximum thickness; 2 hours minimum.

2024年12月10日 · How To Heat Treat O1 Tool Steel？ Annealing. Annealing is a great way to soften O1 steel and relieve any internal stresses. It makes the steel easier to machine and prepares it for the next steps in heat treatment. Heating: Gradually heat the steel to 1450°F (790°C) and hold it at this temperature.

2021年1月19日 · For steel that exhibits such sort of hardness and wears resistance, one would expect it to be equally hard to sharpen. But surprisingly, O1 steel is quite easy to sharpen and does not require you to break your back over it. Heat Treatment of O1 Tool Steel Annealing. Strengthening should be performed after hot working and before re-solidifying.

2024年5月20日 · O1 steel, sometimes called oil-hardening steel, has a unique chemical structure that makes it applicable in many tool making industries. From my own experience, the major elements making up the composition include carbon, …
