class=\"ss-answer\"><p>Both are austenitic grades that work-harden and require good heat and chip control. Their relative machinability depends on composition, supplied condition, product form, and tooling; some supplier ratings are similar. Choose the grade for the service environment, then develop the machining route.<\/p><\/div><\/details>\n      <details><summary>What causes tool wear and dimensional movement?<\/summary><div class=\"ss-answer\"><p>Heat buildup, work hardening, rubbing, poor chip evacuation, and flexible setups can affect tool life and dimensions. Use suitable cutting tools, rigid workholding, consistent engagement, effective coolant, and a planned roughing and finishing sequence.<\/p><\/div><\/details>\n      <details><summary>What is stainless steel made of?<\/summary><div class=\"ss-answer\"><p>Stainless steel is an iron-based alloy containing at least 10.5% chromium. A chromium-rich passive film supports corrosion resistance. Nickel, molybdenum, carbon, sulfur, and other additions change properties such as strength, machinability, weldability, and resistance to specific environments.<\/p><\/div><\/details>\n      <details><summary>Can heat-treated stainless steel be machined?<\/summary><div class=\"ss-answer\"><p>Yes, when the grade, hardness, geometry, and tooling permit. For grades such as 17-4 PH and 420, define the incoming and final conditions, heat-treatment sequence, and finishing allowance. Grinding or final machining may be needed to achieve critical finished features.<\/p><\/div><\/details>\n      <details><summary>Does stainless steel need passivation?<\/summary><div class=\"ss-answer\"><p>Specify passivation when required by the application, drawing, or purchase specification. A suitable process removes free-iron contamination and supports a clean passive surface. It does not replace correct grade selection, scale removal, or a defined corrosion acceptance requirement.<\/p><\/div><\/details>\n    <\/div><\/div>\n    <aside class=\"ss-cta\"><h2>Let's Review Your Stainless Steel Part<\/h2><p>Send your drawing and intended use.
