This extra insulation is especially important when heat treating high-mass loads or running back-to-back cycles.

The KO's side-swing design opens a full 180° to move the door completely out of your way, giving you a clear, safe path to quickly extract your work. This matters most during time-critical quenching operations where seconds count and you need both hands free to handle tongs safely.\u003c\/span\u003e\n\u003c\/div\u003e\n  \u003cdiv class=\"d-faq-item\"\u003e\n\u003cspan class=\"d-q\"\u003eCan this oven handle the heat treating requirements for high-alloy tool steels?\u003c\/span\u003e\u003cspan class=\"d-a\"\u003eYes. The 2400°F maximum temperature covers the austenitizing range for virtually every knife steel you'll encounter, including high-alloy tool steels like CPM-154, S30V, S35VN, and even air-hardening steels like A2 and D2. The special high-temperature element alloy borrowed from ceramic kiln design ensures reliable performance at these extreme temperatures. Most carbon and stainless blade steels require significantly less than 2400°F, so you'll have plenty of headroom.\u003c\/span\u003e\n\u003c\/div\u003e\n  \u003cdiv class=\"d-faq-item\"\u003e\n\u003cspan class=\"d-q\"\u003eWhat does \"second deepest\" mean and what length blades will fit?\u003c\/span\u003e\u003cspan class=\"d-a\"\u003eThe KO 22.5 has a 22.5-inch deep chamber, making it Evenheat's second deepest model in the KO line (only the largest model is deeper).
