\"Carburizing<\/p>\n

VICHOR Carburizing Furnace is a new energy-saving batch-type Heat treatment Furnace. It consists of furnace shell, furnace lining, furnace cover lifting mechanism, vacuum sealed fan, muffle tank, heating elements and etc.<\/p>\n

VICHOR Carburizing Furnace is mainly used for gas carburizing heat treatment of all kinds of steel machinery parts and metal parts such as glaze, gear, mold and etc.<\/p>\n

WHAT IS CARBURIZING?<\/strong><\/p>\n

Any steel part subjected to sliding or rolling requires a hard surface (high carbon content) to resist surface wear. Since most steel parts need to be soft (low carbon content) to allow them to be formed (forged, stamped, cut, etc.) into their desired shape, the hard surface needs to be added after the part is formed.<\/p>\n

HOW DOES THE CARBURIZING PROCESS WORK?<\/strong><\/p>\n

Carburization occurs when a part is placed into a furnace with a furnace atmosphere of almost pure carbon. The part is held at a temperature of 1500-2000 \u00b0F for some prescribed time to achieve the required case depth (depth of the hardened surface).<\/p>\n

Many heat-treating techniques are used to harden the surface of steel parts. The five most common techniques are: Carburizing, nitriding, carbonitriding, flame hardening, and induction hardening. Each technique has its own set of benefits and limits.<\/p>\n

Most steels specified for carburizing contain less than 0.25% carbon, with sufficient alloys to improve case and core hardenability. Depending on the application, any of numerous grades may be used:
\nType 4620 Steel – Lower cost, chrome\/nickel\/molybdenum steel where only nominal hardenability and core response is required.
\nType 8620 Steel – Most commonly specified grade. Excellent carburizing response, with good hardenability for most section sizes.
\nType 4320 Steel – Higher hardenability for improved core response in heavier sections.
\nType 4820 Steel – Increased nickel content for improved core toughness; slower response results in longer process times.
\nType 9310 Steel – Maximum nickel content for maximum core toughness; slower response results in longer process times.
