304/316L Stainless Steel Bright Annealing Furnace

Name: 304/316L Stainless Steel Bright Annealing Furnace
Brand: YuanHang

A professional "Zero-Oxidation" bright heat treatment solution designed for precision metal parts. By utilizing high-vacuum purging and protective atmosphere technology, it ensures that 304/316L stainless steel, copper alloys, and precious metals maintain a mirror-bright finish after annealing, completely eliminating the need for pickling and polishing.

Product details

Product Overview

This series of vacuum atmosphere pit furnaces is engineered for metal components requiring superior surface quality. The equipment features a fully sealed, high-temperature resistant stainless steel muffle tank. Combined with high-vacuum purging and reducing protective atmospheres (H₂/Ar/N₂), it ensures workpieces are completely isolated from oxygen during heating (up to 950°C) and cooling phases.

Key Application Values

Stainless Steel (304/316L, etc.): Eliminates work hardening and internal stress while maintaining a mirror-bright surface, allowing direct transition to the next process.
Copper Alloys: Resolves oxidation and discoloration issues in Beryllium and Oxygen-free copper, ensuring consistent conductivity.
Precious Metals: Ensures extremely low oxidation loss, preserving the original luster of jewelry and luxury goods.
