Stainless Steel 15-5 is a martensitic, precipitation-hardening stainless steel with chromium, nickel, and copper. It offers high strength, hardness, and corrosion resistance, enhanced by heat treatment. It's ideal for applications needing superior corrosion resistance, ductility and toughness.
Stainless Steel 17-4 is a widely used, precipitation-hardening martensitic stainless steel known for its high strength, toughness, and corrosion resistance. It is ideal for applications needing high strength and hardness with reasonable corrosion resistance.
18-8 stainless steel (18% chromium, 8% nickel) offers excellent corrosion resistance and durability. It's easily formed, requires minimal upkeep, and looks appealing. Common applications leverage these properties.
Stainless Steel 303 is a nonmagnetic, austenitic, free-machining type of stainless steel. It is resistant to oxidation until temperatures of 760°C. Moreover, it cannot be hardened with heat treatment, so it is correctly used in parts that require machining.
Diverse industries depend on stainless steel 304 due to its strength and exceptional corrosion resistance. As an austenitic stainless steel, it is used in storage tanks, cutlery, tubing, and kitchen equipment, as well as in architectural panels.
Stainless Steel 316 is composed of chromium, nickel and molybdenum and is preferred for its corrosion resistance. Its primary uses encompass food processing, medical devices, chemicals, cookware, and marine industry. Additionally, its variant 316L is better suited for high-temperature, corrosive environments
Stainless Steel 416 is an economical choice of serrated martensitic stainless steel because of his sulfur and phosphorus content that increases its machinability. Its corrosion resistance is only moderate, but it is ideal for heavily machined parts which require good strength.
Stainless Steel 420 is a Martensitic type of steel that is more useful for high-carbon use fittings such as kitchen knives and scissors, as well as instruments that tend to need wear and tear applications.
Stainless Steel 440C: This high-carbon martensitic steel has excellent hardness, strength, wear resistance, and moderate corrosion resistance. It is ideal for ball bearings, knife blades, and valve components.
Stainless Steel 410 is a martensitic steel with 11.5-13.5% chromium. It offers good corrosion resistance, strength, and hardness and is ideal for cutlery, turbine blades, and fasteners.
AISI 12L14: Resulfurized, rephosphorized carbon steel with lead, offering exceptional machinability; perfect for high-speed machining in fittings, couplings, and bushings.
C45 Steel (AISI 1045): Medium-carbon steel with high tensile strength, good machinability, and moderate wear resistance; ideal for mechanical applications like gears, shafts, and axles.

A: Shops routinely lean on stainless for one-off CNC brackets, test prototypes, and larger production runs needed in auto or aerospace. Because the alloy refuses to rust and laughs at heavy loads, it shows up wherever toughness and cleanliness can’t be traded away.
A: 304 food-grade steel, seawater-resistant 316, and the heat-treated 17-4 PH sound familiar to anyone running a milling spindle. Each lets machinists chase its blend of edge life, smoothness, and corrosion defense. Metal-supply catalogs read like a slice chart of those families.
A: On a CNC lathe, the part spins while a carbide blade creeps in, peeling curls of steel away and leaving a round echo of the program. That moving-center trick locks diameter and finish tight enough for medical shafts and aerospace pins on the first pass. Settings change fast, but the method stays old-school perfect.
A: Stainless-steel stock sits squarely at the crossroads of toughness and polish. Thanks to its high tensile strength, even heavy-cut jobs fly smoothly across its face. Housekeeping is a breeze, and the final piece can shrug off years of wear and tear.
A: Absolutely. A thin film of chromium stitches itself to the surface when oxygen shows up, and that shield repels water, acids, and salt like an invisible raincoat. Harsh shops or seaside installations rarely bother with extra plating.
A: Pricing usually hinges on design intricacy, the exact stainless-steel grade chosen, batch size, and the specific operations, which could be turning, milling, or something else. A quick online calculator will only scratch the surface, so engineers wind up in the office asking for a firm quote once those variables settle.
A: Good carbide inserts, matched feed rates, and a steady coolant flow do most of the lifting, but a brief polish or light anodize at the end gives the surface that smooth, reflective finish. Messy chips left on the part after the last cut can ruin the entire look, so cleanup habit matters too
A: Because in aerospace or medical gear, a half-millimeter off might mean the piece won’t fit or will fail mid-use. That degree of accuracy also reduces rework, shrinks assembly time, and ultimately keeps the whole project on deadline.
A: For sure. Many machining shops work with multiple stainless grades in a single project. Remember that each grade behaves a little differently, so you should lay out your performance and environmental needs before the order is finalized.
