Import Charging Tray For Heat Treatment — Buy in Bulk from Supplier in China

The charging tray for heat treatment from Dongying Changrui Investment Casting Co., Ltd is a cast metal load carrier designed for industrial furnaces and thermal processing systems. It is constructed from high-temperature resistant alloy steel, with a typical thickness of 6 to 10 mm and a load-bearing surface area of up to 1.2 square meters. The tray features reinforced edges and lifting lugs for safe handling under thermal stress, and its open-grid structure allows uniform airflow during heating cycles.

The material composition aligns with standard AISI 310 or equivalent heat-resistant stainless steel grades used in furnace applications. These alloys provide oxidation resistance up to 1150°C and maintain structural integrity under repeated thermal cycling. Typical surface finish is as-cast with minimal machining, avoiding coatings that could flake or contaminate workpieces. Variants include flat-bottomed trays for uniform heat distribution and raised-rail designs for improved gas circulation around loaded parts.

These trays are commonly purchased by metalworking shops, foundries, and automotive component manufacturers conducting annealing, hardening, or tempering operations. Buyers typically order in batches of 10 to 50 units, depending on furnace size and production volume. Trade terms are generally FOB Qingdao or CIF to destination port, with packaging in wooden crates to prevent deformation during transit. Lead time is typically 4 to 6 weeks after order confirmation.
