321 stainless steel plate is a classic titanium-stabilized austenitic stainless steel. With its unique alloy composition and outstanding performance, it plays an indispensable role in many critical industrial fields.
Core components and characteristics
Based on 304 stainless steel, titanium (Ti) is added as a stabilizing element. This crucial improvement enables it to effectively inhibit the precipitation of chromium carbide within the sensitive temperature range of 450-800℃, thereby possessing excellent intergranular corrosion resistance. At the same time, it retains excellent mechanical properties, formability, and outstanding high-temperature oxidation resistance, and can be stably used in intermittent environments up to 900℃ and continuous environments up to 800℃.
Main industrial application scenarios
It is precisely these characteristics that make 321 stainless steel sheet an ideal choice for high-temperature and corrosive environments. Its main applications include:
High-temperature equipment: such as components inside the furnace, heat exchanger tube sheets, boiler insulation covers, etc.
Petroleum and energy industry: Used for manufacturing exhaust pipes, catalytic cracking units, as well as components that require welding and cannot undergo subsequent solidification treatment.
Aerospace and automotive industries: Applied to high-temperature components such as engine exhaust pipes and exhaust systems.
