Manufacture and supply of stainless steel parts

Stainless steel is one of the most popular alloy steels in the industries of high-end precision instruments, semiconductors, and medical equipment. The stainless steel parts manufactured by Boly have good chemical resistance, acid and alkali resistance, and corrosion resistance, and are widely used in mechanical equipment, instrumentation measurement, hydraulic control, and sensor equipment. We have advanced turning and milling machines and surface treatment technology, which enable us to process stainless steel parts with fine surface roughness and precise dimensions according to customer specifications. In addition to corrosion resistance, stainless steel can be welded and is often used for vacuum parts in highly corrosive gas and liquid processes in semiconductors.

For functional parts with high corrosion resistance requirements, we use SUS316/SUS316L stainless steel with added molybdenum element, which makes it excellent in corrosion resistance. Therefore, they are commonly used in the chemical biotechnology industry and are commonly used in food-grade and medical-grade processes, demonstrating excellent quality and efficient performance in applications.

Commonly used stainless: 303, 304, 316, 420, 430, 440C, 630

Advantages of using Stainless steel

In addition to its shiny appearance, high corrosion resistance, stainless steel demonstrates many characteristics that make it suitable for use in machining operations, such as:
Non-magnetic
Strength-to-weight advantage
Excellent fire and heat resistance
Excellent corrosion and impact resistance
Typically doesn’t require surface finishing

Machined components manufactured from a variety of stainless steel grades

Stainless Steel 303

It is a non-magnetic, austenitic stainless steel with good resistance to mildly corrosive atmospheres, but significantly less than 304. Typically used in the manufacture of screw, gears, fittings, bushings, shaft, and more.

Stainless Steel 304/304L

The most common alloy and is known for its pristine surface finish. It has significantly higher corrosion and oxidation resistance. Typically used in the manufacture of sensor parts, shafts, machinery parts, medical parts, and more.

Stainless Steel 316/316L

It is slightly higher levels of chromium and nickel that exhibits improved heat tolerance, resistance to creep and pitting, and excellent tensile strength. Typically used in the manufacture of sensor, chemical & pharmaceutical equipment parts, and more.

Stainless Steel 420

It is a martensitic stainless steel with good corrosion resistance as well as strength and hardness. It is capable of being heat treated to a hardness of HRC 51 minimum. Typically used in the manufacture of pivots, cams, pump shafts, surgical instrument parts, valve components, and more.

Stainless Steel 430

It is a non-hardenable ferritic stainless steel with excellent finish quality. It has good corrosion resistance with good formability and ductility. Typically used in the manufacture of fittings, flanges fasteners, piston, and more.

Stainless Steel 430FR

It is a free-machining solenoid quality alloy, ideal for parts that require corrosion resistance and high electrical resistivity. It has excellent corrosion resistance in fresh water, gaseous, moderately acidic, and low chlorine environments.

Stainless Steel 440C

It is a martensitic stainless steel, and is the highest carbon content from 400 stainless steel series. It is usually heat treated to reach hardness of 58 - 60 HRC. Typically used in the manufacture of valve seats, piston, shaft, and more.

Stainless Steel 630

It is commonly referred to as 17-4 and is a precipitation-hardening martensitic stainless steel that offers superior corrosion resistance. It is magnetic, readily welded. Typically used in the manufacture of sensor housing, valve, pump shaft, and more.
