High-alloy steels like D2 and A2 can be hardened at this temperature, though some premium stainless steels requiring higher austenitizing temperatures (S30V, S35VN) may need specialized equipment. The atmosphere capability allows protective gas during heat treating to prevent decarburization on high-carbon steels. For tempering cycles, this oven handles all steel types from 300°F to 1000°F.\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"d-faq-item\"\u003e\n    \u003cdiv class=\"d-q\"\u003eCan I introduce atmosphere into the chamber during heat treating?\u003c\/div\u003e\n    \u003cdiv class=\"d-a\"\u003eYes, the HS-18K includes a gas inlet port specifically for introducing protective atmosphere during heat treating. Most knife makers use argon or nitrogen to prevent oxidation and scale formation on blade surfaces during austenitizing. This is especially important for high-carbon steels that are prone to decarburization at elevated temperatures. You'll need a separate gas regulator and delivery system, which can be purchased as an optional accessory. Always ensure proper ventilation when using atmosphere gases.\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"d-faq-item\"\u003e\n    \u003cdiv class=\"d-q\"\u003eWhat's the difference between 120V and 240V models?\u003c\/div\u003e\n    \u003cdiv class=\"d-a\"\u003eThe 120V model plugs into a standard household outlet, making it convenient for small shops without dedicated electrical service. However, the 240V model heats faster and maintains temperature more efficiently during extended heat treating sessions or when door is opened frequently. If you're heat treating multiple blades per day or working with larger stock, the 240V option reduces cycle times significantly. Consult with a licensed electrician to determine which voltage is best for your electrical service and production needs.\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"d-faq-item\"\u003e\n    \u003cdiv class=\"d-q\"\u003eDoes this oven include the digital controller and solid state relay?\u003c\/div\u003e\n    \u003cdiv class=\"d-a\"\u003eYes, the HS-18K comes standard with both a digital controller and solid state relay (SSR). The SSR is critical for knife making because it extends element life and provides smoother temperature control during critical austenitizing holds. Unlike cheaper on\/off controllers that cycle power abruptly, the solid state relay gradually modulates power for precise temperature maintenance within ±5°F. This precision is essential when heat treating steels with narrow hardening temperature windows.\u003c\/div\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"d-faq-item\"\u003e\n    \u003cdiv class=\"d-q\"\u003eIs my warranty valid if I don't buy from an authorized dealer?\u003c\/div\u003e\n    \u003cdiv class=\"d-a\"\u003eNo. Hot Shot warranties are only valid when purchased through authorized dealers like Peach State Pottery. Ovens purchased from unauthorized resellers, auction sites, or private parties have no manufacturer warranty coverage. Additionally, you must register your oven within 30 days of delivery to activate the one-year limited warranty. Authorized dealers provide proper documentation, support technical questions, and facilitate warranty service if needed.\u003c\/div\u003e\n  \u003c\/div\u003e\n\n\u003c\/div\u003e\n\n\u003cdiv class=\"d-cta\"\u003e\n  \u003cdiv\u003e\n    \u003cspan class=\"d-cta-title\"\u003eNot sure if the HS-18K is the right heat treating oven for your knife shop?\u003c\/span\u003e\n    \u003cspan class=\"d-cta-sub\"\u003eOur team can help you compare chamber sizes, voltage requirements, and atmosphere capabilities for your specific steel types and production volume.\u003c\/span\u003e\n  \u003c\/div\u003e\n  \u003ca href=\"https:\/\/peachstatepottery.com\/pages\/contact-us\" class=\"d-cta-link\"\u003eTalk to an expert →\u003c\/a\u003e\n\u003c\/div\u003e\n\n\u003c\/div\u003e","brand":"HotShot Oven \u0026 Kiln","offers":[{"title":"Default Title","offer_id":48456872329371,"sku":"HS-18K","price":3292.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0757\/7160\/9243\/files\/22-AMROT-1368-026-Select_e2_800x_c41cef30-60f5-474a-9a99-7e28e4cf7778.webp?v=1777342246","url":"https:\/\/peachstatepottery.com\/products\/hot-shot-knife-makers-kiln-hs-18k","provider":"Peach State Pottery","version":"1.0","type":"link"}
