It looks like you're referencing a specification or product description for a heavy-duty industrial blower. Let me break down what each part of that description typically means in the context of foundry equipment:

"Heavy Duty Foundry Stainless Steel Blower"

• Heavy Duty: Designed for continuous operation in harsh environments (high temperatures, dust, vibration).
• Foundry: Intended for use in metal casting facilities. This means the blower must handle hot air, fumes, and particulate matter (sand, metal dust).
• Stainless Steel: The blower housing, impeller, or both are made of stainless steel. This is crucial for corrosion resistance (from moisture or chemical fumes) and for maintaining integrity at high temperatures. Common grades are 304 or 316, though for foundry use, 310S (heat-resistant) or 309 are sometimes used.

"Anti Abrasive"

• This means the blower is designed to resist wear from abrasive particles in the airstream. In a foundry, this could be sand, scale, or metal shavings.
• How it's achieved: Often through thicker material, hardened impellers, replaceable wear liners, or a special coating. In the case of "stainless steel," the material itself is tough, but anti-abrasive features might include a thicker impeller or a special surface treatment.

"16Mn"

• This is a Chinese standard steel grade (GB/T 1591).
• 16Mn is a low-alloy, high-strength structural steel with a yield strength of about 345 MPa.
• Crucial point: 16Mn is not stainless steel. It is a carbon-manganese steel.
• The contradiction: You are describing a "Stainless Steel Blower" but specifying 16Mn (a non-stainless steel). This is a conflict.

What this likely means (and what you need to check):

There are two common scenarios:

Scenario A: You are looking at a mismatched or misleading description. A vendor might be selling a blower that has a 16Mn steel housing (for strength and abrasion resistance) but a stainless steel impeller (for heat/corrosion). However, the description lumps it all together incorrectly. You need to clarify:

• Is the housing 16Mn and the impeller stainless?
• Or is the entire blower 16Mn (meaning it is not stainless)?

Scenario B: You intend "16Mn" as a high-strength backing material for the blower shaft or mounting, not the blower body. Sometimes the shaft of a heavy-duty blower is made of 16Mn (or 40Cr) for strength, while the impeller and housing are stainless. But "blower" usually refers to the whole unit.

Recommendation for a Real Foundry Blower:

If you need a Heavy Duty Foundry Anti-Abrasive Blower, here is what a proper specification would look like:

Bottom Line:

• 16Mn is a strong, wear-resistant steel but it will rust. It is ideal for anti-abrasive fan impellers in dusty foundry environments.
• Stainless Steel is corrosion and heat resistant but generally softer and more expensive.
• You cannot have a blower that is both fully 16Mn and fully Stainless Steel.

What to ask the supplier:

"Is the impeller made of 16Mn for abrasion resistance, and the housing made of stainless steel? Or is the entire unit 16Mn? Please provide a material certificate for the impeller and the casing separately."

If you need a blower that combines abrasion resistance (16Mn) and corrosion/heat resistance (Stainless), expect a hybrid design (one part 16Mn, one part SS). If you are looking for a single material, you must choose based on priority: Abrasion (choose 16Mn) or Heat/Corrosion (choose Stainless Steel grade like 310S).
