FSUE CRIM is able to produce springs from different types of metals and alloys.

Heatproof and fire-resistant nickeliferous alloys and springs

are efficient from - 253о

Springs Mark	Temperature range (оС)	Time period
ЭИ 828	up to 850	briefly
	up to 750	long-term
ЭИ 437Б	up to 500	long-term

Advantages:
• Resistance to radiation exposure;
• Corrosion resistance.

Heat-resistant alloy of niobium «ЛН-1»

is functional from: - 196°С

Temperature range (оС)	Time period
up to 1200	briefly
up to 1000	long-term in a vacuum
up to 800	long-term in the liquid casting

Advantages:
• high energy;

Extrahigh tensile (σв >1400 MPa) β-titanium alloy

is functional from 196°С to 400°С.


Advantages:
• increasing of power capacity in 1,5-2 times and relaxation capability and reduction of the volume of spring in 1,5-2 times compared with springs of steels «65С2ВА» and «60С2ХВА».
• effective suppression period of shock and vibration loads.
• increased allowable stress level by 20%
• two times higher relaxation capability, with shock loads, compared with spring steel «65С2ВА» and «60С2ХВА».

Extrahigh tensile stainless steel

are functional from -196оС

Springs brands	Temperature range oC(оС)	Time period
12Х18Н10Т	Up to 300	Long-term

Advantages:
• Resistance in sea water, marine atmosphere, hot water, HNO3
