Why use vermicular graphite alloy cast-iron to make piston rings?

At present, the big, medium and small rings are widely applied throughout the world. Including, flake graphite alloy cast-iron, vermicular graphite alloy cast-iron and spherical graphite alloy cast-iron.

Following are main performance indicators of such three materials.

No.	Performance Indicator	Flake Graphite Alloy Cast-iron	Vermicular Graphite Alloy Cast-iron	Spherical Graphite Alloy Cast-iron
1	Hardness	HRB95-108 HB200-300	HRB98-110 HB230-300	HRB100-110
2	Bending Strengthδw:N/mm2	≥400	＞600	＞1100
3	Modulus of elasticity: N/mm2	85000-110000	≥130000	≥150000
4	Thermal (tangential elasticity disappearance rate)	≤15%	≤8%	≤8%
5	Wear resistance and sorting by sizes	Second	First	Third
6	Thermal conductivity λCaL/cm•s℃	First 0.10-0.12	Second 0.09-0.10	Third 0.07-0.08
7	Linear expansion coefficient (within range of 20°~300℃ mm/mm℃	aP(11.0-12.0)×10^-6	aR12×10^-6	aQ12.3×10^-6
8	Anti-fusion wear capacity(cylinder scoring) and sorting by sizes	First	Second	Third
9	Corrosion resistance and sorting by sizes	Third	Second	First
10	Fatigue strength δ-1 and sorting by sizes	Third	Second	First
11	Impact toughness and sorting by sizes ak:J/cm2 or kg-m/cm2	aP-K Third	aR-K Second	aQ-K First

From the above 11 indicators, the eight performance indicators of vermicular graphite alloy cast-iron are all superior over the flake graphite alloy cast-iron, including:

•Hardness

•Bending Strength

•Modulus of elasticity

•Wear resistance

•Thermal (tangential elasticity disappearance rate)

•Corrosion resistance

•Fatigue strength δ-1

•Impact toughness

And other six performance indicators are superior over the spherical graphite alloy cast-iron,including:

•Hardness

•Linear expansion coefficient

•Thermal (tangential elasticity disappearance rate)

•Wear resistance

•Thermal conductivity

•Anti-fusion wear capacity

In addition,the vermicular cast-iron rings have been used for many years as the first gas rings in the high-speed or high horsepower diesel engines and proven that they are safe and reliable, the vermicular cast-iron rings have a good comprehensive application performance.

So it is the best option to use vermicular graphite alloy cast-iron as the first gas ring material in the high-speed or high horsepower marine diesel engines.

The vermicular graphite alloy cast-iron is a sheet-like structure, similar to the tip of the bamboo leaf is round, the pieces are interlocked, the three-dimensional structure, the internal graphite forms a natural oil storage passage, so the product has very good flexibility, which is N times that of the gray cast iron.

The use of vermicular graphite alloy cast-iron in the first gas ring is a major feature of our company. We use single-piece casting process and barrel casting process; small batch and multi-batch production; complete model; fast delivery; coverable cylinder diameter is φ150~φ1000mm; service life is up to 20,000 hours, about 2~3 years.

We use electroplating, composite plating and phosphating for heat treatment.

From the four aspects of hardness, elasticity, light transmission, and geometrical dimensions, all are tested.

We have the first CNC internal and external circular elliptical copying lathe, which can produce various types of piston rings according to user's actual sample or design drawings.

At present, we are the only company that uses vermicular graphite alloy cast-iron as the first gas ring material in the high-speed or high horsepower marine diesel engines in China. Our goal is to become an OE supplier for two-stroke low-speed marine piston ring.
